Notes to Shareholders:

As discussed in prior shareholder reports, the fund changed its investment approach in the way it invests in the investment-grade debt market, seeking exposure to various types of securities by investing in central funds as well as investing directly in individual investment-grade securities. Central funds are Fidelity mutual funds used by this fund and other Fidelity funds as an investment vehicle to gain pooled exposure to a particular core market sector, such as corporate bonds or mortgage-backed securities. Instead of multiple funds each investing in investment-grade debt securities individually, they can now take advantage of consolidating investments in a single, larger pool of investment-grade debt by investing directly in central funds. Shares of the central funds are offered only to other Fidelity mutual funds and accounts; investors cannot directly invest in them.

It's important to point out that investing in central funds does not impact the fund's investment objective or risk profile, only the mechanics of how we manage its investment portfolio. The portfolio managers continue to be responsible for choosing appropriate investments for their funds, whether they elect to purchase shares of a central fund or individual securities. Fidelity does not charge any additional management fees for central funds.

Investing in central funds does change the way this report presents the fund's holdings. The Investments section continues to list direct investments of the fund, including each central fund. However, many of the individual investment-grade debt securities previously held by the fund were transferred to the central funds, so they are no longer directly held and thus not listed. Information on the underlying holdings of the fixed-income central funds is available at advisor.fidelity.com, and the financial statements are available upon request.

Chairman's Message

(photo_of_Edward_C_Johnson_3d)

Dear Shareholder:

Substantial single-day losses are not uncommon in the equity markets, and when they occur - as in late February - investors can be better served in the long term by buying good stocks at lower prices than by moving their money to the sidelines. While financial markets are always unpredictable, there are a number of time-tested principles that can put the historical odds in your favor.

One of the basic tenets is to invest for the long term. Over time, riding out the markets' inevitable ups and downs has proven much more effective than selling into panic or chasing the hottest trend. Even missing only a few of the markets' best days can significantly diminish investor returns. Patience also affords the benefits of compounding - of earning interest on additional income or reinvested dividends and capital gains. There are tax advantages and cost benefits to consider as well. The more you sell, the more taxes you pay, and the more you trade, the higher the costs. While staying the course doesn't eliminate risk, it can considerably lessen the effect of short-term declines.

You can further manage your investing risk through diversification. And today, more than ever, geographic diversification should be taken into account. Studies indicate that asset allocation is the single most important determinant of a portfolio's long-term success. The right mix of stocks, bonds and cash - aligned to your particular risk tolerance and investment objective - is very important. Age-appropriate rebalancing is also an essential aspect of asset allocation. For younger investors, an emphasis on equities - which historically have been the best performing asset class over time - is encouraged. As investors near their specific goal, such as retirement or sending a child to college, consideration may be given to replacing volatile assets (e.g. common stocks) with more-stable fixed investments (bonds or savings plans).

A third investment principle - investing regularly - can help lower the average cost of your purchases. Investing a certain amount of money each month or quarter helps ensure you won't pay for all your shares at market highs. This strategy - known as dollar cost averaging - also reduces unconstructive "emotion" from investing, helping shareholders avoid selling weak performers just prior to an upswing, or chasing a hot performer just before a correction.

We invite you to contact us via the Internet, through our Investor Centers or over the phone. It is our privilege to provide you the information you need to make the investments that are right for you.

Sincerely,

/s/Edward C. Johnson 3d

Shareholder Expense Example

As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including sales charges (loads) on purchase payments or redemption proceeds, and (2) ongoing costs, including management fees, distribution and/or service (12b-1) fees and other Fund expenses. This Example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds.

The Example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period (September 1, 2006 to February 28, 2007).

Actual Expenses

The first line of the accompanying table for each class of the Fund provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000.00 (for example, an $8,600 account value divided by $1,000.00 = 8.6), then multiply the result by the number in the first line for a class of the Fund under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. In addition, the Fund, as a shareholder in the underlying Fidelity Central Funds, will indirectly bear its pro rata share of the fees and expenses incurred by the underlying Fidelity Central Funds. These fees and expenses are not included in the Fund's annualized expense ratio used to calculate the expense estimate in the table below.

Hypothetical Example for Comparison Purposes

The second line of the accompanying table for each class of the Fund provides information about hypothetical account values and hypothetical expenses based on a Class' actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Class' actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. In addition, the Fund, as a shareholder in the underlying Fidelity Central Funds, will indirectly bear its pro rata share of the fees and expenses incurred by the underlying Fidelity Central Funds. These fees and expenses are not included in the Fund's annualized expense ratio used to calculate the expense estimate in the table below.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transaction costs. Therefore, the second line of the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

Duration shows how much a bond fund's price fluctuates with changes in comparable interest rates. If rates rise 1%, for example, a fund with a five-year duration is likely to lose about 5% of its value. Other factors also can influence a bond fund's performance and share price. Accordingly, a bond fund's actual performance may differ from this example.

1. Organization.

Fidelity Advisor Intermediate Bond Fund (the Fund) is a fund of Fidelity Advisor Series II (the trust) and is authorized to issue an unlimited number of shares. The trust is registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company organized as a Massachusetts business trust. The Fund offers Class A, Class T, Class B, Class C and Institutional Class shares, each of which has equal rights as to assets and voting privileges. Each class has exclusive voting rights with respect to matters that affect that class. Class B shares will automatically convert to Class A shares after a holding period of four years from the initial date of purchase. Investment income, realized and unrealized capital gains and losses, the common expenses of the Fund, and certain fund-level expense reductions, if any, are allocated on a pro rata basis to each class based on the relative net assets of each class to the total net assets of the Fund. Each class differs with respect to transfer agent and distribution and service plan fees incurred. Certain expense reductions also differ by class. The financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America, which require management to make certain estimates and assumptions at the date of the financial statements.

2. Investments in Fidelity Central Funds.

The Fund may invest in Fidelity Central Funds which are open-end investment companies available only to other investment companies and accounts managed by Fidelity Management & Research Company (FMR) and its affiliates. The Fund's Schedule of Investments lists each of the Fidelity Central Funds as an investment of the Fund but does not include the underlying holdings of each Fidelity Central Fund. As an Investing Fund, the Fund indirectly bears its proportionate share of the expenses of the underlying Fidelity Central Funds. A complete unaudited list of holdings for each Fidelity Central Fund is available upon request or for the Fixed-Income Central Funds, at advisor.fidelity.com. The reports are located just after the Fund's financial statements and quarterly reports but are not part of the financial statements or quarterly reports. In addition, the financial statements of the Fidelity Central Funds, are available on the EDGAR Database on the SEC's web site, www.sec.gov, or upon request.

Based on their investment objective, each Fidelity Central Fund may invest or participate in various investment vehicles or strategies that are similar to those of the Fund. These strategies are consistent with the investment objectives of the Fund and may involve certain economic risks which may cause a decline in value of each of the Fidelity Central Funds and thus a decline in the value of the Fund. The following summarizes the Fund's investment in each Fidelity Central Fund.

3. Significant Accounting Policies.

The following summarizes the significant accounting policies of the Fund:

Security Valuation. Investments are valued and net asset value per share is calculated (NAV calculation) as of the close of business of the New York Stock Exchange, normally 4:00 p.m. Eastern time. Wherever possible, the Fund uses independent pricing services approved by the Board of Trustees to value its investments. Debt securities, including restricted securities, for which quotations are readily available, are valued by independent pricing services or by dealers who make markets in such securities. Pricing services consider yield or price of bonds of comparable quality, coupon, maturity and type as well as dealer supplied prices. When current market prices or quotations are not readily available or do not accurately reflect fair value, valuations may be determined in accordance with procedures adopted by the Board of Trustees. The frequency of when fair value pricing is used is unpredictable. The value of securities used for NAV calculation under fair value pricing may differ from published prices for the same securities. Investments in open-end mutual funds, including the Fidelity Central Funds, are valued at their closing net asset value each business day. Short-term securities with remaining maturities of sixty days or less for which quotations are not readily available are valued at amortized cost, which approximates value.

Investment Transactions and Income. For financial reporting purposes, the Fund's investment holdings and NAV include trades executed through the end of the last business day of the period. The NAV for processing shareholder transactions includes trades executed through the end of the prior business day. Gains and losses on securities sold are determined on the basis of identified cost and may include proceeds received from litigation. Interest income and income and capital gain distributions from the Fidelity Central Funds are accrued as earned, with any distributions receivable as of period end included in Distributions receivable from Fidelity Central Funds on the Statement of Assets and Liabilities. Interest income includes coupon interest and amortization of premium and accretion of discount on debt securities. Inflation-indexed bonds are fixed-income securities whose principal value is periodically adjusted to the rate of inflation. Interest is accrued based on the principal value, which is adjusted for inflation. Any increase in the principal amount of an inflation-indexed bond is recorded as interest income, even though principal is not received until maturity.

Expenses. Most expenses of the trust can be directly attributed to a fund. Expenses which cannot be directly attributed are apportioned among each Fund in the trust. Expense estimates are accrued in the period to which they relate and adjustments are made when actual amounts are known.

3. Significant Accounting Policies - continued

Income Tax Information and Distributions to Shareholders. Each year, the Fund intends to qualify as a regulated investment company by distributing all of its taxable income and realized gains under Subchapter M of the Internal Revenue Code. As a result, no provision for income taxes is required in the accompanying financial statements.

Dividends are declared daily and paid monthly from net investment income. Distributions from realized gains, if any, are recorded on the ex-dividend date. Income dividends and capital gain distributions are declared separately for each class. Income and capital gain distributions are determined in accordance with income tax regulations, which may differ from generally accepted accounting principles.

Capital accounts within the financial statements are adjusted for permanent book-tax differences. These adjustments have no impact on net assets or the results of operations. Temporary book-tax differences will reverse in a subsequent period.

Book-tax differences are primarily due to swap agreements, prior period premium and discount on debt securities, market discount, partnerships (including allocations from Fidelity Central Funds, deferred trustees compensation, financing transactions, capital loss carryforwards and losses deferred due to wash sales.

The federal tax cost of investments and unrealized appreciation (depreciation) as of period end were as follows:

Unrealized appreciation

$ 9,434,653

Unrealized depreciation

(7,854,249)

Net unrealized appreciation (depreciation)

New Accounting Pronouncements. In July 2006, Financial Accounting Standards Board Interpretation No. 48, Accounting for Uncertainty in Income Taxes - an interpretation of FASB Statement 109 (FIN 48), was issued and is effective on the last business day of the semiannual reporting period for fiscal years beginning after December 15, 2006. FIN 48 sets forth a threshold for financial statement recognition, measurement and disclosure of a tax position taken or expected to be taken on a tax return. Management is currently evaluating the impact, if any, the adoption of FIN 48 will have on the Fund's net assets, results of operations and financial statement disclosures.

In addition, in September 2006, Statement of Financial Accounting Standards No. 157, Fair Value Measurements (SFAS 157), was issued and is effective for fiscal years beginning after November 15, 2007. SFAS 157 defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. Management is currently evaluating the impact the adoption of SFAS 157 will have on the Fund's financial statement disclosures.

Semiannual Report

4. Operating Policies.

Repurchase Agreements. FMR has received an Exemptive Order from the Securities and Exchange Commission (the SEC) which permits the Fund and other affiliated entities of FMR to transfer uninvested cash balances into joint trading accounts which are then invested in repurchase agreements. The Fund may also invest directly with institutions in repurchase agreements. Repurchase agreements are collateralized by government or non-government securities. Upon settlement date, collateral is held in segregated accounts with custodian banks and may be obtained in the event of a default of the counterparty. The Fund monitors, on a daily basis, the value of the collateral to ensure it is at least equal to the principal amount of the repurchase agreement (including accrued interest). In the event of a default by the counterparty, realization of the collateral proceeds could be delayed, during which time the value of the collateral may decline.

Delayed Delivery Transactions and When-Issued Securities. The Fund may purchase or sell securities on a delayed delivery or when-issued basis. Payment and delivery may take place after the customary settlement period for that security. The price of the underlying securities and the date when the securities will be delivered and paid for are fixed at the time the transaction is negotiated. During the time a delayed delivery sell is outstanding, the contract is marked-to-market daily and equivalent deliverable securities are held for the transaction. The value of the securities purchased on a delayed delivery or when-issued basis are identified as such in the Fund's Schedule of Investments. The Fund may receive compensation for interest forgone in the purchase of a delayed delivery or when-issued security. With respect to purchase commitments, the Fund identifies securities as segregated in its records with a value at least equal to the amount of the commitment. Losses may arise due to changes in the value of the underlying securities or if the counterparty does not perform under the contract's terms, or if the issuer does not issue the securities due to political, economic, or other factors.

Restricted Securities. The Fund may invest in securities that are subject to legal or contractual restrictions on resale. These securities generally may be resold in transactions exempt from registration or to the public if the securities are registered. Disposal of these securities may involve time-consuming negotiations and expense, and prompt sale at an acceptable price may be difficult. Information regarding restricted securities is included at the end of the Fund's Schedule of Investments.

Swap Agreements. The Fund may invest in swaps for the purpose of managing its exposure to interest rate, credit or market risk.

Interest rate swaps are agreements to exchange cash flows periodically based on a notional principal amount, for example, the exchange of fixed rate interest payments for floating rate interest payments. Periodic payments received or made by the Fund are

Semiannual Report

Swap Agreements - continued

recorded in the accompanying Statement of Operations as realized gains or losses, respectively. The primary risk associated with interest rate swaps is that unfavorable changes in the fluctuation of interest rates could adversely impact a fund.

Credit default swaps involve the exchange of a fixed rate premium for protection against the loss in value of an underlying debt instrument in the event of a defined credit event (such as payment default or bankruptcy). Under the terms of the swap, one party acts as a "guarantor" receiving a periodic payment that is a fixed percentage applied to a notional principal amount. In return the party agrees to purchase the notional amount of the underlying instrument, at par, if a credit event occurs during the term of the swap. The Fund may enter into credit default swaps in which either it or its counterparty act as guarantors. By acting as the guarantor of a swap, a fund assumes the market and credit risk of the underlying instrument including liquidity and loss of value. Periodic payments and premiums received or made by the Fund are recorded in the accompanying Statement of Operations as realized gains or losses, respectively.

Swaps are marked-to-market daily based on dealer-supplied valuations and changes in value are recorded as unrealized appreciation (depreciation). Gains or losses are realized upon early termination of the swap agreement. Collateral, in the form of cash or securities, may be required to be held in segregated accounts with a fund's custodian in compliance with swap contracts. Risks may exceed amounts recognized on the Statement of Assets and Liabilities. These risks include changes in the returns of the underlying instruments, failure of the counterparties to perform under the contracts' terms and the possible lack of liquidity with respect to the swap agreements. Details of swap agreements open at period end are included in the Fund's Schedule of Investments under the caption "Swap Agreements."

Mortgage Dollar Rolls. To earn additional income, the Fund may employ trading strategies which involve the sale and simultaneous agreement to repurchase similar securities ("mortgage dollar rolls") or the purchase and simultaneous agreement to sell similar securities ("reverse mortgage dollar rolls"). The securities traded are mortgage securities and bear the same interest rate but may be collateralized by different pools of mortgages. During the period between the sale and repurchase in a mortgage dollar roll transaction, a fund will not be entitled to receive interest and principal payments on the securities sold but will invest the proceeds of the sale in other securities which may enhance the yield and total return. In addition, the difference between the sale price and the future purchase price is recorded as an adjustment to investment income. During the period between the purchase and subsequent sale in a reverse mortgage dollar roll transaction a fund is entitled to interest and principal payments on the securities

4. Operating Policies - continued

Mortgage Dollar Rolls - continued

purchased. The price differential between the purchase and sale is recorded as an adjustment to investment income. Losses may arise due to changes in the value of the securities or if the counterparty does not perform under the terms of the agreement. If the counterparty files for bankruptcy or becomes insolvent, a fund's right to repurchase or sell securities may be limited.

5. Purchases and Sales of Investments.

Purchases and sales of securities (including the Fixed-Income Central Funds), other than short-term securities, U.S. government securities and in-kind transactions, aggregated $197,524,141 and $98,533,945, respectively.

6. Fees and Other Transactions with Affiliates.

Management Fee. FMR and its affiliates provide the Fund with investment management related services for which the Fund pays a monthly management fee. The management fee is the sum of an individual fund fee rate that is based on an annual rate of .20% of the Fund's average net assets and a group fee rate that averaged .12% during the period. The group fee rate is based upon the average net assets of all the mutual funds advised by FMR. The group fee rate decreases as assets under management increase and increases as assets under management decrease. For the period, the total annualized management fee rate was .32% of the Fund's average net assets.

Distribution and Service Plan. In accordance with Rule 12b-1 of the 1940 Act, the Fund has adopted separate Distribution and Service Plans for each class of shares. Certain classes pay Fidelity Distributors Corporation (FDC), an affiliate of FMR, separate Distribution and Service Fees, each of which is based on an annual percentage of each class' average net assets. In addition, FDC may pay financial intermediaries for selling shares of the Fund and providing shareholder support services. For the period, the Distribution and Service Fee rates and the total amounts paid to and retained by FDC were as follows:

Sales Load. FDC receives a front-end sales charge of up to 3.75% for selling Class A shares, and 2.75% for selling Class T shares, some of which is paid to financial intermediaries for selling shares of the Fund. FDC receives the proceeds of contingent deferred sales charges levied on Class A, Class T, Class B, and Class C redemptions. These charges depend on the holding period. The deferred sales charges range from 3% to 1% for Class B, 1% for Class C, .75% to .50% for certain purchases of Class A shares and .25% for certain purchases of Class T shares.

On January 18, 2007, the Board of Trustees approved a change in Class A's front-end sales charge. Effective April 1, 2007, FDC will receive a front-end sales charge of up to 2.75% for selling Class A shares.

Accounting and Security Lending Fees. Fidelity Service Company, Inc. (FSC), an affiliate of FMR, maintains the Fund's accounting records. The accounting fee is based on the level of average net assets for the month. Under a separate contract, FSC administers the security lending program. The security lending fee is based on the number and duration of lending transactions.

Exchange-In-Kind. During the period, the Fund exchanged securities for shares of four newly created Fidelity Fixed-Income Central Funds, all of which are affiliated investment companies managed by FIMM, an affiliate of FMR. The Fund delivered securities to each Fixed-Income Central Fund in exchange for shares of each respective Fixed-Income Central Fund, as presented in the accompanying table. Each exchange is considered a non-taxable exchange for federal income tax purposes, with no gain or loss recognized by the Fund or its shareholders.

7. Committed Line of Credit.

The Fund participates with other funds managed by FMR in a $4.2 billion credit facility (the "line of credit") to be utilized for temporary or emergency purposes to fund shareholder redemptions or for other short-term liquidity purposes. The Fund has agreed to pay commitment fees on its pro rata portion of the line of credit, which amounted to $1,896 and is reflected in Miscellaneous Expense on the Statement of Operations. During the period, there were no borrowings on this line of credit.

8. Security Lending.

The Fund lends portfolio securities from time to time in order to earn additional income. On the settlement date of the loan, the Fund receives collateral (in the form of U.S. Treasury obligations, letters of credit and/or cash) against the loaned securities and maintains collateral in an amount not less than 100% of the market value of the loaned

Semiannual Report

Notes to Financial Statements (Unaudited) - continued

8. Security Lending - continued

securities during the period of the loan. The market value of the loaned securities is determined at the close of business of the Fund and any additional required collateral is delivered to the Fund on the next business day. If the borrower defaults on its obligation to return the securities loaned because of insolvency or other reasons, a fund could experience delays and costs in recovering the securities loaned or in gaining access to the collateral. Any cash collateral received is invested in cash equivalents. The value of loaned securities and cash collateral at period end are disclosed on the Fund's Statement of Assets and Liabilities. Security lending income represents the income earned on investing cash collateral, less fees and expenses associated with the loan, plus any premium payments that may be received on the loan of certain types of securities. Security lending income is presented in the Statement of Operations as a component of interest income. Net income from lending portfolio securities during the period amounted to $68,128.

9. Expense Reductions.

Through arrangements with the Fund's custodian and each class' transfer agent, credits realized as a result of uninvested cash balances were used to reduce the Fund's expenses. During the period, these credits reduced the Fund's custody expenses by $5,361. During the period, credits reduced each class' transfer agent expense as noted in the table below.

10. Other.

The Fund's organizational documents provide former and current trustees and officers with a limited indemnification against liabilities arising in connection with the performance of their duties to the Fund. In the normal course of business, the Fund may also enter into contracts that provide general indemnifications. The Fund's maximum exposure under these arrangements is unknown as this would be dependent on future claims that may be made against the Fund. The risk of material loss from such claims is considered remote.

10. Other - continued

During the period, the Fund's transfer agent, Fidelity Investments Institutional Operations Company, Inc. (FIIOC), an affiliate of Fidelity Management & Research Company, notified the Fund that the fund's books and records did not reflect a conversion of certain Class B to Class A shares upon their conversion date. Management has determined that this did not have a material impact to the Fund's reported net assets or results of operations in the accompanying financial statements. In March 2007, FIIOC converted the relevant Class B shares to Class A shares and recorded the conversion in the books and records of the Fund. FIIOC has reimbursed the Fund for related audit and legal expenses and is in the process of determining appropriate remediation to affected shareholder accounts.

Semiannual Report

Notes to Shareholders:

As discussed in prior shareholder reports, the fund changed its investment approach in the way it invests in the investment-grade debt market, seeking exposure to various types of securities by investing in central funds as well as investing directly in individual investment-grade securities. Central funds are Fidelity mutual funds used by this fund and other Fidelity funds as an investment vehicle to gain pooled exposure to a particular core market sector, such as corporate bonds or mortgage-backed securities. Instead of multiple funds each investing in investment-grade debt securities individually, they can now take advantage of consolidating investments in a single, larger pool of investment-grade debt by investing directly in central funds. Shares of the central funds are offered only to other Fidelity mutual funds and accounts; investors cannot directly invest in them.

It's important to point out that investing in central funds does not impact the fund's investment objective or risk profile, only the mechanics of how we manage its investment portfolio. The portfolio managers continue to be responsible for choosing appropriate investments for their funds, whether they elect to purchase shares of a central fund or individual securities. Fidelity does not charge any additional management fees for central funds.

Investing in central funds does change the way this report presents the fund's holdings. The Investments section continues to list direct investments of the fund, including each central fund. However, many of the individual investment-grade debt securities previously held by the fund were transferred to the central funds, so they are no longer directly held and thus not listed. Information on the underlying holdings of the fixed-income central funds is available at advisor.fidelity.com, and the financial statements are available upon request.

Chairman's Message

(photo_of_Edward_C_Johnson_3d)

Dear Shareholder:

Substantial single-day losses are not uncommon in the equity markets, and when they occur - as in late February - investors can be better served in the long term by buying good stocks at lower prices than by moving their money to the sidelines. While financial markets are always unpredictable, there are a number of time-tested principles that can put the historical odds in your favor.

One of the basic tenets is to invest for the long term. Over time, riding out the markets' inevitable ups and downs has proven much more effective than selling into panic or chasing the hottest trend. Even missing only a few of the markets' best days can significantly diminish investor returns. Patience also affords the benefits of compounding - of earning interest on additional income or reinvested dividends and capital gains. There are tax advantages and cost benefits to consider as well. The more you sell, the more taxes you pay, and the more you trade, the higher the costs. While staying the course doesn't eliminate risk, it can considerably lessen the effect of short-term declines.

You can further manage your investing risk through diversification. And today, more than ever, geographic diversification should be taken into account. Studies indicate that asset allocation is the single most important determinant of a portfolio's long-term success. The right mix of stocks, bonds and cash - aligned to your particular risk tolerance and investment objective - is very important. Age-appropriate rebalancing is also an essential aspect of asset allocation. For younger investors, an emphasis on equities - which historically have been the best performing asset class over time - is encouraged. As investors near their specific goal, such as retirement or sending a child to college, consideration may be given to replacing volatile assets (e.g. common stocks) with more-stable fixed investments (bonds or savings plans).

A third investment principle - investing regularly - can help lower the average cost of your purchases. Investing a certain amount of money each month or quarter helps ensure you won't pay for all your shares at market highs. This strategy - known as dollar cost averaging - also reduces unconstructive "emotion" from investing, helping shareholders avoid selling weak performers just prior to an upswing, or chasing a hot performer just before a correction.

We invite you to contact us via the Internet, through our Investor Centers or over the phone. It is our privilege to provide you the information you need to make the investments that are right for you.

Sincerely,

/s/Edward C. Johnson 3d

Shareholder Expense Example

As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including sales charges (loads) on purchase payments or redemption proceeds, and (2) ongoing costs, including management fees, distribution and/or service (12b-1) fees and other Fund expenses. This Example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds.

The Example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period (September 1, 2006 to February 28, 2007).

Actual Expenses

The first line of the accompanying table for each class of the Fund provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000.00 (for example, an $8,600 account value divided by $1,000.00 = 8.6), then multiply the result by the number in the first line for a class of the Fund under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. In addition, the Fund, as a shareholder in the underlying Fidelity Central Funds, will indirectly bear its pro rata share of the fees and expenses incurred by the underlying Fidelity Central Funds. These fees and expenses are not included in the Fund's annualized expense ratio used to calculate the expense estimate in the table below.

Hypothetical Example for Comparison Purposes

The second line of the accompanying table for each class of the Fund provides information about hypothetical account values and hypothetical expenses based on a Class' actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Class' actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. In addition, the Fund, as a shareholder in the underlying Fidelity Central Funds, will indirectly bear its pro rata share of the fees and expenses incurred by the underlying Fidelity Central Funds. These fees and expenses are not included in the Fund's annualized expense ratio used to calculate the expense estimate in the table below.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transaction costs. Therefore, the second line of the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

Duration shows how much a bond fund's price fluctuates with changes in comparable interest rates. If rates rise 1%, for example, a fund with a five-year duration is likely to lose about 5% of its value. Other factors also can influence a bond fund's performance and share price. Accordingly, a bond fund's actual performance may differ from this example.

1. Organization.

Fidelity Advisor Intermediate Bond Fund (the Fund) is a fund of Fidelity Advisor Series II (the trust) and is authorized to issue an unlimited number of shares. The trust is registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company organized as a Massachusetts business trust. The Fund offers Class A, Class T, Class B, Class C and Institutional Class shares, each of which has equal rights as to assets and voting privileges. Each class has exclusive voting rights with respect to matters that affect that class. Class B shares will automatically convert to Class A shares after a holding period of four years from the initial date of purchase. Investment income, realized and unrealized capital gains and losses, the common expenses of the Fund, and certain fund-level expense reductions, if any, are allocated on a pro rata basis to each class based on the relative net assets of each class to the total net assets of the Fund. Each class differs with respect to transfer agent and distribution and service plan fees incurred. Certain expense reductions also differ by class. The financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America, which require management to make certain estimates and assumptions at the date of the financial statements.

2. Investments in Fidelity Central Funds.

The Fund may invest in Fidelity Central Funds which are open-end investment companies available only to other investment companies and accounts managed by Fidelity Management & Research Company (FMR) and its affiliates. The Fund's Schedule of Investments lists each of the Fidelity Central Funds as an investment of the Fund but does not include the underlying holdings of each Fidelity Central Fund. As an Investing Fund, the Fund indirectly bears its proportionate share of the expenses of the underlying Fidelity Central Funds. A complete unaudited list of holdings for each Fidelity Central Fund is available upon request or for the Fixed-Income Central Funds, at advisor.fidelity.com. The reports are located just after the Fund's financial statements and quarterly reports but are not part of the financial statements or quarterly reports. In addition, the financial statements of the Fidelity Central Funds, are available on the EDGAR Database on the SEC's web site, www.sec.gov, or upon request.

Based on their investment objective, each Fidelity Central Fund may invest or participate in various investment vehicles or strategies that are similar to those of the Fund. These strategies are consistent with the investment objectives of the Fund and may involve certain economic risks which may cause a decline in value of each of the Fidelity Central Funds and thus a decline in the value of the Fund. The following summarizes the Fund's investment in each Fidelity Central Fund.

3. Significant Accounting Policies.

The following summarizes the significant accounting policies of the Fund:

Security Valuation. Investments are valued and net asset value per share is calculated (NAV calculation) as of the close of business of the New York Stock Exchange, normally 4:00 p.m. Eastern time. Wherever possible, the Fund uses independent pricing services approved by the Board of Trustees to value its investments. Debt securities, including restricted securities, for which quotations are readily available, are valued by independent pricing services or by dealers who make markets in such securities. Pricing services consider yield or price of bonds of comparable quality, coupon, maturity and type as well as dealer supplied prices. When current market prices or quotations are not readily available or do not accurately reflect fair value, valuations may be determined in accordance with procedures adopted by the Board of Trustees. The frequency of when fair value pricing is used is unpredictable. The value of securities used for NAV calculation under fair value pricing may differ from published prices for the same securities. Investments in open-end mutual funds, including the Fidelity Central Funds, are valued at their closing net asset value each business day. Short-term securities with remaining maturities of sixty days or less for which quotations are not readily available are valued at amortized cost, which approximates value.

Investment Transactions and Income. For financial reporting purposes, the Fund's investment holdings and NAV include trades executed through the end of the last business day of the period. The NAV for processing shareholder transactions includes trades executed through the end of the prior business day. Gains and losses on securities sold are determined on the basis of identified cost and may include proceeds received from litigation. Interest income and income and capital gain distributions from the Fidelity Central Funds are accrued as earned, with any distributions receivable as of period end included in Distributions receivable from Fidelity Central Funds on the Statement of Assets and Liabilities. Interest income includes coupon interest and amortization of premium and accretion of discount on debt securities. Inflation-indexed bonds are fixed-income securities whose principal value is periodically adjusted to the rate of inflation. Interest is accrued based on the principal value, which is adjusted for inflation. Any increase in the principal amount of an inflation-indexed bond is recorded as interest income, even though principal is not received until maturity.

Expenses. Most expenses of the trust can be directly attributed to a fund. Expenses which cannot be directly attributed are apportioned among each Fund in the trust. Expense estimates are accrued in the period to which they relate and adjustments are made when actual amounts are known.

3. Significant Accounting Policies - continued

Income Tax Information and Distributions to Shareholders. Each year, the Fund intends to qualify as a regulated investment company by distributing all of its taxable income and realized gains under Subchapter M of the Internal Revenue Code. As a result, no provision for income taxes is required in the accompanying financial statements.

Dividends are declared daily and paid monthly from net investment income. Distributions from realized gains, if any, are recorded on the ex-dividend date. Income dividends and capital gain distributions are declared separately for each class. Income and capital gain distributions are determined in accordance with income tax regulations, which may differ from generally accepted accounting principles.

Capital accounts within the financial statements are adjusted for permanent book-tax differences. These adjustments have no impact on net assets or the results of operations. Temporary book-tax differences will reverse in a subsequent period.

Book-tax differences are primarily due to swap agreements, prior period premium and discount on debt securities, market discount, partnerships (including allocations from Fidelity Central Funds, deferred trustees compensation, financing transactions, capital loss carryforwards and losses deferred due to wash sales.

The federal tax cost of investments and unrealized appreciation (depreciation) as of period end were as follows:

Unrealized appreciation

$ 9,434,653

Unrealized depreciation

(7,854,249)

Net unrealized appreciation (depreciation)

$ 1,798,001,655

New Accounting Pronouncements. In July 2006, Financial Accounting Standards Board Interpretation No. 48, Accounting for Uncertainty in Income Taxes - an interpretation of FASB Statement 109 (FIN 48), was issued and is effective on the last business day of the semiannual reporting period for fiscal years beginning after December 15, 2006. FIN 48 sets forth a threshold for financial statement recognition, measurement and disclosure of a tax position taken or expected to be taken on a tax return. Management is currently evaluating the impact, if any, the adoption of FIN 48 will have on the Fund's net assets, results of operations and financial statement disclosures.

In addition, in September 2006, Statement of Financial Accounting Standards No. 157, Fair Value Measurements (SFAS 157), was issued and is effective for fiscal years beginning after November 15, 2007. SFAS 157 defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. Management is currently evaluating the impact the adoption of SFAS 157 will have on the Fund's financial statement disclosures.

Semiannual Report

4. Operating Policies.

Repurchase Agreements. FMR has received an Exemptive Order from the Securities and Exchange Commission (the SEC) which permits the Fund and other affiliated entities of FMR to transfer uninvested cash balances into joint trading accounts which are then invested in repurchase agreements. The Fund may also invest directly with institutions in repurchase agreements. Repurchase agreements are collateralized by government or non-government securities. Upon settlement date, collateral is held in segregated accounts with custodian banks and may be obtained in the event of a default of the counterparty. The Fund monitors, on a daily basis, the value of the collateral to ensure it is at least equal to the principal amount of the repurchase agreement (including accrued interest). In the event of a default by the counterparty, realization of the collateral proceeds could be delayed, during which time the value of the collateral may decline.

Delayed Delivery Transactions and When-Issued Securities. The Fund may purchase or sell securities on a delayed delivery or when-issued basis. Payment and delivery may take place after the customary settlement period for that security. The price of the underlying securities and the date when the securities will be delivered and paid for are fixed at the time the transaction is negotiated. During the time a delayed delivery sell is outstanding, the contract is marked-to-market daily and equivalent deliverable securities are held for the transaction. The value of the securities purchased on a delayed delivery or when-issued basis are identified as such in the Fund's Schedule of Investments. The Fund may receive compensation for interest forgone in the purchase of a delayed delivery or when-issued security. With respect to purchase commitments, the Fund identifies securities as segregated in its records with a value at least equal to the amount of the commitment. Losses may arise due to changes in the value of the underlying securities or if the counterparty does not perform under the contract's terms, or if the issuer does not issue the securities due to political, economic, or other factors.

Restricted Securities. The Fund may invest in securities that are subject to legal or contractual restrictions on resale. These securities generally may be resold in transactions exempt from registration or to the public if the securities are registered. Disposal of these securities may involve time-consuming negotiations and expense, and prompt sale at an acceptable price may be difficult. Information regarding restricted securities is included at the end of the Fund's Schedule of Investments.

Swap Agreements. The Fund may invest in swaps for the purpose of managing its exposure to interest rate, credit or market risk.

Interest rate swaps are agreements to exchange cash flows periodically based on a notional principal amount, for example, the exchange of fixed rate interest payments for floating rate interest payments. Periodic payments received or made by the Fund are

Semiannual Report

Notes to Financial Statements (Unaudited) - continued

Swap Agreements - continued

recorded in the accompanying Statement of Operations as realized gains or losses, respectively. The primary risk associated with interest rate swaps is that unfavorable changes in the fluctuation of interest rates could adversely impact a fund.

Credit default swaps involve the exchange of a fixed rate premium for protection against the loss in value of an underlying debt instrument in the event of a defined credit event (such as payment default or bankruptcy). Under the terms of the swap, one party acts as a "guarantor" receiving a periodic payment that is a fixed percentage applied to a notional principal amount. In return the party agrees to purchase the notional amount of the underlying instrument, at par, if a credit event occurs during the term of the swap. The Fund may enter into credit default swaps in which either it or its counterparty act as guarantors. By acting as the guarantor of a swap, a fund assumes the market and credit risk of the underlying instrument including liquidity and loss of value. Periodic payments and premiums received or made by the Fund are recorded in the accompanying Statement of Operations as realized gains or losses, respectively.

Swaps are marked-to-market daily based on dealer-supplied valuations and changes in value are recorded as unrealized appreciation (depreciation). Gains or losses are realized upon early termination of the swap agreement. Collateral, in the form of cash or securities, may be required to be held in segregated accounts with a fund's custodian in compliance with swap contracts. Risks may exceed amounts recognized on the Statement of Assets and Liabilities. These risks include changes in the returns of the underlying instruments, failure of the counterparties to perform under the contracts' terms and the possible lack of liquidity with respect to the swap agreements. Details of swap agreements open at period end are included in the Fund's Schedule of Investments under the caption "Swap Agreements."

Mortgage Dollar Rolls. To earn additional income, the Fund may employ trading strategies which involve the sale and simultaneous agreement to repurchase similar securities ("mortgage dollar rolls") or the purchase and simultaneous agreement to sell similar securities ("reverse mortgage dollar rolls"). The securities traded are mortgage securities and bear the same interest rate but may be collateralized by different pools of mortgages. During the period between the sale and repurchase in a mortgage dollar roll transaction, a fund will not be entitled to receive interest and principal payments on the securities sold but will invest the proceeds of the sale in other securities which may enhance the yield and total return. In addition, the difference between the sale price and the future purchase price is recorded as an adjustment to investment income. During the period between the purchase and subsequent sale in a reverse mortgage dollar roll transaction a fund is entitled to interest and principal payments on the securities

4. Operating Policies - continued

Mortgage Dollar Rolls - continued

purchased. The price differential between the purchase and sale is recorded as an adjustment to investment income. Losses may arise due to changes in the value of the securities or if the counterparty does not perform under the terms of the agreement. If the counterparty files for bankruptcy or becomes insolvent, a fund's right to repurchase or sell securities may be limited.

5. Purchases and Sales of Investments.

Purchases and sales of securities (including the Fixed-Income Central Funds), other than short-term securities, U.S. government securities and in-kind transactions, aggregated $197,524,141 and $98,533,945, respectively.

6. Fees and Other Transactions with Affiliates.

Management Fee. FMR and its affiliates provide the Fund with investment management related services for which the Fund pays a monthly management fee. The management fee is the sum of an individual fund fee rate that is based on an annual rate of .20% of the Fund's average net assets and a group fee rate that averaged .12% during the period. The group fee rate is based upon the average net assets of all the mutual funds advised by FMR. The group fee rate decreases as assets under management increase and increases as assets under management decrease. For the period, the total annualized management fee rate was .32% of the Fund's average net assets.

Distribution and Service Plan. In accordance with Rule 12b-1 of the 1940 Act, the Fund has adopted separate Distribution and Service Plans for each class of shares. Certain classes pay Fidelity Distributors Corporation (FDC), an affiliate of FMR, separate Distribution and Service Fees, each of which is based on an annual percentage of each class' average net assets. In addition, FDC may pay financial intermediaries for selling shares of the Fund and providing shareholder support services. For the period, the Distribution and Service Fee rates and the total amounts paid to and retained by FDC were as follows:

Sales Load. FDC receives a front-end sales charge of up to 3.75% for selling Class A shares, and 2.75% for selling Class T shares, some of which is paid to financial intermediaries for selling shares of the Fund. FDC receives the proceeds of contingent deferred sales charges levied on Class A, Class T, Class B, and Class C redemptions. These charges depend on the holding period. The deferred sales charges range from 3% to 1% for Class B, 1% for Class C, .75% to .50% for certain purchases of Class A shares and .25% for certain purchases of Class T shares.

On January 18, 2007, the Board of Trustees approved a change in Class A's front-end sales charge. Effective April 1, 2007, FDC will receive a front-end sales charge of up to 2.75% for selling Class A shares.

6. Fees and Other Transactions with Affiliates - continued

Accounting and Security Lending Fees. Fidelity Service Company, Inc. (FSC), an affiliate of FMR, maintains the Fund's accounting records. The accounting fee is based on the level of average net assets for the month. Under a separate contract, FSC administers the security lending program. The security lending fee is based on the number and duration of lending transactions.

Exchange-In-Kind. During the period, the Fund exchanged securities for shares of four newly created Fidelity Fixed-Income Central Funds, all of which are affiliated investment companies managed by FIMM, an affiliate of FMR. The Fund delivered securities to each Fixed-Income Central Fund in exchange for shares of each respective Fixed-Income Central Fund, as presented in the accompanying table. Each exchange is considered a non-taxable exchange for federal income tax purposes, with no gain or loss recognized by the Fund or its shareholders.

7. Committed Line of Credit.

The Fund participates with other funds managed by FMR in a $4.2 billion credit facility (the "line of credit") to be utilized for temporary or emergency purposes to fund shareholder redemptions or for other short-term liquidity purposes. The Fund has agreed to pay commitment fees on its pro rata portion of the line of credit, which amounted to $1,896 and is reflected in Miscellaneous Expense on the Statement of Operations. During the period, there were no borrowings on this line of credit.

8. Security Lending.

The Fund lends portfolio securities from time to time in order to earn additional income. On the settlement date of the loan, the Fund receives collateral (in the form of U.S. Treasury obligations, letters of credit and/or cash) against the loaned securities and maintains collateral in an amount not less than 100% of the market value of the loaned

Notes to Financial Statements (Unaudited) - continued

8. Security Lending - continued

securities during the period of the loan. The market value of the loaned securities is determined at the close of business of the Fund and any additional required collateral is delivered to the Fund on the next business day. If the borrower defaults on its obligation to return the securities loaned because of insolvency or other reasons, a fund could experience delays and costs in recovering the securities loaned or in gaining access to the collateral. Any cash collateral received is invested in cash equivalents. The value of loaned securities and cash collateral at period end are disclosed on the Fund's Statement of Assets and Liabilities. Security lending income represents the income earned on investing cash collateral, less fees and expenses associated with the loan, plus any premium payments that may be received on the loan of certain types of securities. Security lending income is presented in the Statement of Operations as a component of interest income. Net income from lending portfolio securities during the period amounted to $68,128.

9. Expense Reductions.

Through arrangements with the Fund's custodian and each class' transfer agent, credits realized as a result of uninvested cash balances were used to reduce the Fund's expenses. During the period, these credits reduced the Fund's custody expenses by $5,361. During the period, credits reduced each class' transfer agent expense as noted in the table below.

10. Other.

The Fund's organizational documents provide former and current trustees and officers with a limited indemnification against liabilities arising in connection with the performance of their duties to the Fund. In the normal course of business, the Fund may also enter into contracts that provide general indemnifications. The Fund's maximum exposure under these arrangements is unknown as this would be dependent on future claims that may be made against the Fund. The risk of material loss from such claims is considered remote.

Semiannual Report

10. Other - continued

During the period, the Fund's transfer agent, Fidelity Investments Institutional Operations Company, Inc. (FIIOC), an affiliate of Fidelity Management & Research Company, notified the Fund that the fund's books and records did not reflect a conversion of certain Class B to Class A shares upon their conversion date. Management has determined that this did not have a material impact to the Fund's reported net assets or results of operations in the accompanying financial statements. In March 2007, FIIOC converted the relevant Class B shares to Class A shares and recorded the conversion in the books and records of the Fund. FIIOC has reimbursed the Fund for related audit and legal expenses and is in the process of determining appropriate remediation to affected shareholder accounts.

Chairman's Message

(photo_of_Edward_C_Johnson_3d)

Dear Shareholder:

Substantial single-day losses are not uncommon in the equity markets, and when they occur - as in late February - investors can be better served in the long term by buying good stocks at lower prices than by moving their money to the sidelines. While financial markets are always unpredictable, there are a number of time-tested principles that can put the historical odds in your favor.

One of the basic tenets is to invest for the long term. Over time, riding out the markets' inevitable ups and downs has proven much more effective than selling into panic or chasing the hottest trend. Even missing only a few of the markets' best days can significantly diminish investor returns. Patience also affords the benefits of compounding - of earning interest on additional income or reinvested dividends and capital gains. There are tax advantages and cost benefits to consider as well. The more you sell, the more taxes you pay, and the more you trade, the higher the costs. While staying the course doesn't eliminate risk, it can considerably lessen the effect of short-term declines.

You can further manage your investing risk through diversification. And today, more than ever, geographic diversification should be taken into account. Studies indicate that asset allocation is the single most important determinant of a portfolio's long-term success. The right mix of stocks, bonds and cash - aligned to your particular risk tolerance and investment objective - is very important. Age-appropriate rebalancing is also an essential aspect of asset allocation. For younger investors, an emphasis on equities - which historically have been the best performing asset class over time - is encouraged. As investors near their specific goal, such as retirement or sending a child to college, consideration may be given to replacing volatile assets (e.g. common stocks) with more-stable fixed investments (bonds or savings plans).

A third investment principle - investing regularly - can help lower the average cost of your purchases. Investing a certain amount of money each month or quarter helps ensure you won't pay for all your shares at market highs. This strategy - known as dollar cost averaging - also reduces unconstructive "emotion" from investing, helping shareholders avoid selling weak performers just prior to an upswing, or chasing a hot performer just before a correction.

We invite you to contact us via the Internet, through our Investor Centers or over the phone. It is our privilege to provide you the information you need to make the investments that are right for you.

Sincerely,

/s/Edward C. Johnson 3d

Edward C. Johnson 3d

Semiannual Report

Shareholder Expense Example

As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including sales charges (loads) on purchase payments or redemption proceeds, and (2) ongoing costs, including management fees, distribution and/or service (12b-1) fees and other Fund expenses. This Example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds.

The Example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period (September 1, 2006 to February 28, 2007).

Actual Expenses

The first line of the accompanying table for each class of the Fund provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000.00 (for example, an $8,600 account value divided by $1,000.00 = 8.6), then multiply the result by the number in the first line for a class of the Fund under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. In addition, the Fund, as a shareholder in the underlying Fidelity Central Funds, will indirectly bear its pro rata share of the fees and expenses incurred by the underlying Fidelity Central Funds. These fees and expenses are not included in the Fund's annualized expense ratio used to calculate the expense estimate in the table below.

Hypothetical Example for Comparison Purposes

The second line of the accompanying table for each class of the Fund provides information about hypothetical account values and hypothetical expenses based on a Class' actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Class' actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. In addition, the Fund, as a shareholder in the underlying Fidelity Central Funds, will indirectly bear its pro rata share of the fees and expenses incurred by the underlying Fidelity Central Funds. These fees and expenses are not included in the Fund's annualized expense ratio used to calculate the expense estimate in the table below.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transaction costs. Therefore, the second line of the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

Duration shows how much a bond fund's price fluctuates with changes in comparable interest rates. If rates rise 1%, for example, a fund with a five-year duration is likely to lose about 5% of its value. Other factors also can influence a bond fund's performance and share price. Accordingly, a bond fund's actual performance may differ from this example.

1. Organization.

Fidelity Advisor Mortgage Securities Fund (the Fund) is a fund of Fidelity Advisor Series II (the trust) and is authorized to issue an unlimited number of shares. The trust is registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company organized as a Massachusetts business trust. The Fund offers Class A, Class T, Class B, Class C, Fidelity Mortgage Securities Fund, and Institutional Class shares, each of which has equal rights as to assets and voting privileges. Each class has exclusive voting rights with respect to matters that affect that class. Class B shares will automatically convert to Class A shares after a holding period of seven years from the initial date of purchase. Investment income, realized and unrealized capital gains and losses, the common expenses of the Fund, and certain fund-level expense reductions, if any, are allocated on a pro rata basis to each class based on the relative net assets of each class to the total net assets of the Fund. Each class differs with respect to transfer agent and distribution and service plan fees incurred. Certain expense reductions also differ by class. The financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America, which require management to make certain estimates and assumptions at the date of the financial statements.

2. Investments in Fidelity Central Funds.

The Fund may invest in Fidelity Central Funds which are open-end investment companies available only to other investment companies and accounts managed by Fidelity Management & Research Company (FMR) and its affiliates. The Fund's Schedule of Investments lists each of the Fidelity Central Funds as an investment of the Fund but does not include the underlying holdings of each Fidelity Central Fund. As an Investing Fund, the Fund indirectly bears its proportionate share of the expenses of the underlying Fidelity Central Funds. A complete unaudited list of holdings for each Fidelity Central Fund is available upon request or, for the Fixed-Income Central Funds, at fidelity.com and/or advisor.fidelity.com, as applicable. The reports are located just after the Fund's financial statements and quarterly reports but are not part of the financial statements or quarterly reports. In addition, the financial statements of the Fidelity Central Funds, are available on the EDGAR Database on the SEC's web site, www.sec.gov, or upon request.

Based on their investment objective, each Fidelity Central Fund may invest or participate in various investment vehicles or strategies that are similar to those of the Fund. These strategies are consistent with the investment objectives of the Fund and may involve certain economic risks which may cause a decline in value of each of the Fidelity

3. Significant Accounting Policies.

The following summarizes the significant accounting policies of the Fund:

Security Valuation. Investments are valued and net asset value per share is calculated (NAV calculation) as of the close of business of the New York Stock Exchange, normally 4:00 p.m. Eastern time. Wherever possible, the Fund uses independent pricing services approved by the Board of Trustees to value its investments. Debt securities, including restricted securities, for which quotes are readily available, are valued by independent pricing services or by dealers who make markets in such securities. Pricing services consider yield or price of bonds of comparable quality, coupon, maturity and type as well as dealer supplied prices. When current market prices or quotations are not readily available or do not accurately reflect fair value, valuations may be determined in accordance with procedures adopted by the Board of Trustees. The frequency of when fair value pricing is used is unpredictable. The value of securities used for NAV calculation under fair value pricing may differ from published prices for the same securities. Investments in open-end mutual funds, including the Fidelity Central Funds, are valued at their closing net asset value each business day. Short-term securities with remaining maturities of sixty days or less for which quotations are not readily available are valued at amortized cost, which approximates value.

Investment Transactions and Income. For financial reporting purposes, the Fund's investment holdings and NAV include trades executed through the end of the last business day of the period. The NAV for processing shareholder transactions includes trades executed through the end of the prior business day. Gains and losses on securities sold are determined on the basis of identified cost. Interest income and income and capital gain distributions from the Fidelity Central Funds are accrued as earned, with

Investment Transactions and Income - continued

any distributions receivable as of period end included in Distributions receivable from Fidelity Central Funds on the Statement of Assets and Liabilities. Interest income includes coupon interest and amortization of premium and accretion of discount on debt securities.

Expenses. Most expenses of the trust can be directly attributed to a fund. Expenses which cannot be directly attributed are apportioned among each Fund in the trust. Expense estimates are accrued in the period to which they relate and adjustments are made when actual amounts are known.

Income Tax Information and Distributions to Shareholders. Each year, the Fund intends to qualify as a regulated investment company by distributing all of its taxable income and realized gains under Subchapter M of the Internal Revenue Code. As a result, no provision for income taxes is required in the accompanying financial statements.

Dividends are declared daily and paid monthly from net investment income. Distributions from realized gains, if any, are recorded on the ex-dividend date. Income dividends and capital gain distributions are declared separately for each class. Income and capital gain distributions are determined in accordance with income tax regulations, which may differ from generally accepted accounting principles.

Capital accounts within the financial statements are adjusted for permanent book-tax differences. These adjustments have no impact on net assets or the results of operations. Temporary book-tax differences will reverse in a subsequent period.

Book-tax differences are primarily due to prior period premium and discount on debt securities, market discount, deferred trustees compensation, financing transactions, capital loss carryforwards and losses deferred due to wash sales.

The federal tax cost of investments and unrealized appreciation (depreciation) as of period end were as follows:

Unrealized appreciation

$ 12,304

New Accounting Pronouncements. In July 2006, Financial Accounting Standards Board Interpretation No. 48, Accounting for Uncertainty in Income Taxes - an interpretation of FASB Statement 109 (FIN 48), was issued and is effective on the last business day of the semiannual reporting period for fiscal years beginning after December 15,

(Amounts in thousands except ratios)

3. Significant Accounting Policies - continued

New Accounting Pronouncements - continued

2006. FIN 48 sets forth a threshold for financial statement recognition, measurement and disclosure of a tax position taken or expected to be taken on a tax return. Management is currently evaluating the impact, if any, the adoption of FIN 48 will have on the Fund's net assets, results of operations and financial statement disclosures.

In addition, in September 2006, Statement of Financial Accounting Standards No. 157, Fair Value Measurements (SFAS 157), was issued and is effective for fiscal years beginning after November 15, 2007. SFAS 157 defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. Management is currently evaluating the impact the adoption of SFAS 157 will have on the Fund's financial statement disclosures.

4. Operating Policies.

Repurchase Agreements. FMR has received an Exemptive Order from the Securities and Exchange Commission (the SEC) which permits the Fund and other affiliated entities of FMR to transfer uninvested cash balances into joint trading accounts which are then invested in repurchase agreements. The Fund may also invest directly with institutions in repurchase agreements. Repurchase agreements are collateralized by government or non-government securities. Upon settlement date, collateral is held in segregated accounts with custodian banks and may be obtained in the event of a default of the counterparty. The Fund monitors, on a daily basis, the value of the collateral to ensure it is at least equal to the principal amount of the repurchase agreement (including accrued interest). In the event of a default by the counterparty, realization of the collateral proceeds could be delayed, during which time the value of the collateral may decline.

Delayed Delivery Transactions and When-Issued Securities. The Fund may purchase or sell securities on a delayed delivery or when-issued basis. Payment and delivery may take place after the customary settlement period for that security. The price of the underlying securities and the date when the securities will be delivered and paid for are fixed at the time the transaction is negotiated. During the time a delayed delivery sell is outstanding, the contract is marked-to-market daily and equivalent deliverable securities are held for the transaction. The value of the securities purchased on a delayed delivery or when-issued basis are identified as such in the Fund's Schedule of Investments. The Fund may receive compensation for interest forgone in the purchase of a delayed delivery or when-issued security. With respect to purchase commitments, the

Semiannual Report

4. Operating Policies - continued

Delayed Delivery Transactions and When-Issued Securities - continued

Fund identifies securities as segregated in its records with a value at least equal to the amount of the commitment. Losses may arise due to changes in the value of the underlying securities or if the counterparty does not perform under the contract's terms, or if the issuer does not issue the securities due to political, economic, or other factors.

Restricted Securities. The Fund may invest in securities that are subject to legal or contractual restrictions on resale. These securities generally may be resold in transactions exempt from registration or to the public if the securities are registered. Disposal of these securities may involve time-consuming negotiations and expense, and prompt sale at an acceptable price may be difficult. Information regarding restricted securities is included at the end of the Fund's Schedule of Investments.

Swap Agreements. The Fund may invest in swaps for the purpose of managing its exposure to interest rate, credit or market risk.

Interest rate swaps are agreements to exchange cash flows periodically based on a notional principal amount, for example, the exchange of fixed rate interest payments for floating rate interest payments. Periodic payments received or made by the Fund are recorded in the accompanying Statement of Operations as realized gains or losses, respectively. The primary risk associated with interest rate swaps is that unfavorable changes in the fluctuation of interest rates could adversely impact a fund.

Total return swaps are agreements to exchange the return generated by one instrument or index for the return generated by another instrument, for example, the agreement to pay interest in exchange for a market-linked return based on a notional amount. To the extent the total return of the index exceeds the offsetting interest obligation, a fund will receive a payment from the counterparty. To the extent it is less, a fund will make a payment to the counterparty. Periodic payments received or made by the Fund are recorded in the accompanying Statement of Operations as realized gains or losses, respectively.

Credit default swaps involve the exchange of a fixed rate premium for protection against the loss in value of an underlying debt instrument in the event of a defined credit event (such as payment default or bankruptcy). Under the terms of the swap, one party acts as a "guarantor" receiving a periodic payment that is a fixed percentage applied to a notional principal amount. In return the party agrees to purchase the notional amount of the underlying instrument, at par, if a credit event occurs during the term of the swap. The Fund may enter into credit default swaps in which either it or its counterparty act as

Semiannual Report

Notes to Financial Statements (Unaudited) - continued

(Amounts in thousands except ratios)

4. Operating Policies - continued

Swap Agreements - continued

guarantors. By acting as the guarantor of a swap, a fund assumes the market and credit risk of the underlying instrument including liquidity and loss of value. Periodic payments and premiums received or made by the Fund are recorded in the accompanying Statement of Operations as realized gains or losses, respectively.

Swaps are marked-to-market daily based on dealer-supplied valuations and changes in value are recorded as unrealized appreciation (depreciation). Gains or losses are realized upon early termination of the swap agreement. Collateral, in the form of cash or securities, may be required to be held in segregated accounts with a fund's custodian in compliance with swap contracts. Risks may exceed amounts recognized on the Statement of Assets and Liabilities. These risks include changes in the returns of the underlying instruments, failure of the counterparties to perform under the contracts' terms and the possible lack of liquidity with respect to the swap agreements. Details of swap agreements open at period end are included in the Fund's Schedule of Investments under the caption "Swap Agreements."

Mortgage Dollar Rolls. To earn additional income, the Fund may employ trading strategies which involve the sale and simultaneous agreement to repurchase similar securities ("mortgage dollar rolls") or the purchase and simultaneous agreement to sell similar securities ("reverse mortgage dollar rolls"). The securities traded are mortgage securities and bear the same interest rate but may be collateralized by different pools of mortgages. During the period between the sale and repurchase in a mortgage dollar roll transaction, a fund will not be entitled to receive interest and principal payments on the securities sold but will invest the proceeds of the sale in other securities which may enhance the yield and total return. In addition, the difference between the sale price and the future purchase price is recorded as an adjustment to investment income. During the period between the purchase and subsequent sale in a reverse mortgage dollar roll transaction a fund is entitled to interest and principal payments on the securities purchased. The price differential between the purchase and sale is recorded as an adjustment to investment income. Losses may arise due to changes in the value of the securities or if the counterparty does not perform under the terms of the agreement. If the counterparty files for bankruptcy or becomes insolvent, a fund's right to repurchase or sell securities may be limited.

5. Purchases and Sales of Investments.

Purchases and sales of securities (including the Fixed-Income Central Funds), other than short-term securities and U.S. government securities, aggregated $467,402 and $286,584, respectively.

Semiannual Report

6. Fees and Other Transactions with Affiliates.

Management Fee. FMR and its affiliates provide the Fund with investment management related services for which the Fund pays a monthly management fee. The management fee is the sum of an individual fund fee rate that is based on an annual rate of .20% of the Fund's average net assets and a group fee rate that averaged .12% during the period. The group fee rate is based upon the average net assets of all the mutual funds advised by FMR. The group fee rate decreases as assets under management increase and increases as assets under management decrease. For the period, the total annualized management fee rate was .32% of the Fund's average net assets.

Distribution and Service Plan. In accordance with Rule 12b-1 of the 1940 Act, the Fund has adopted separate Distribution and Service Plans for each class of shares. Certain classes pay Fidelity Distributors Corporation (FDC), an affiliate of FMR, separate Distribution and Service Fees, each of which is based on an annual percentage of each class' average net assets. In addition, FDC may pay financial intermediaries for selling shares of the Fund and providing shareholder support services. For the period, the Distribution and Service Fee rates and the total amounts paid to and retained by FDC were as follows:

On January 18, 2007, the Board of Trustees approved an increase in Class A's Service fee from .15% to .25%, effective April 1, 2007.

Sales Load. FDC receives a front-end sales charge of up to 4.75% for selling Class A shares, and 3.50% for selling Class T shares, some of which is paid to financial intermediaries for selling shares of the Fund. FDC receives the proceeds of contingent deferred sales charges levied on Class A, Class T, Class B, and Class C redemptions. These charges depend on the holding period. The deferred sales charges range from 5% to 1% for Class B, 1% for Class C, .75% to .50% for certain purchases of Class A shares and .25% for certain purchases of Class T shares.

On January 18, 2007, the Board of Trustees approved a change in Class A and Class T's front-end sales charge. Effective April 1, 2007, FDC will receive a front-end sales charge of up to 4.00% for selling Class A and Class T shares.

* When Class B and Class C shares are initially sold, FDC pays commissions from its own resources to financial intermediaries through which the sales
are made.

Transfer Agent Fees. Fidelity Investments Institutional Operations Company, Inc. (FIIOC), an affiliate of FMR, is the transfer, dividend disbursing and shareholder servicing agent for each class of the Fund, except for Fidelity Mortgage Securities Fund. Fidelity Service Company, Inc. (FSC), an affiliate of FMR, is the transfer agent for Fidelity Mortgage Securities Fund shares. FIIOC receives account fees and asset-based fees that vary according to the account size and type of account of the shareholders of the respective classes of the Fund. FSC receives an asset-based fee of .10% of Fidelity Mortgage Securities Fund's average net assets. FIIOC and FSC pay for typesetting, printing and mailing of shareholder reports, except proxy statements. For the period, the total transfer agent fees paid by each class to FIIOC or FSC, were as follows:

Fundwide Operations Fee. Pursuant to the Fundwide Operations and Expense Agreement (FWOE), FMR has agreed to provide for fund level expenses (which do not include transfer agent, Rule 12b-1 fees, compensation of the independent trustees, interest (including commitment fees), taxes or extraordinary expenses, if any) in return

for a FWOE fee equal to .35% less the total amount of the management fee. The FWOE paid by the Fund is reduced by an amount equal to the fees and expenses paid to the independent trustees. For the period, the FWOE fee was equivalent to an annualized rate of .03% of average net assets.

7. Committed Line of Credit.

The Fund participates with other funds managed by FMR in a $4.2 billion credit facility (the "line of credit") to be utilized for temporary or emergency purposes to fund shareholder redemptions or for other short-term liquidity purposes. The Fund has agreed to pay commitment fees on its pro rata portion of the line of credit, which amounted to $2 and is reflected in Miscellaneous Expense on the Statement of Operations. During the period, there were no borrowings on this line of credit.

8. Expense Reductions.

Through arrangements with the Fund's custodian and each class' transfer agent, credits realized as a result of uninvested cash balances were used to reduce the Fund's expenses. During the period, these credits reduced the Fund's management fee by $3. During the period, credits reduced each class' transfer agent expense as noted in the table below.

9. Other.

The Fund's organizational documents provide former and current trustees and officers with a limited indemnification against liabilities arising in connection with the performance of their duties to the Fund. In the normal course of business, the Fund may also enter into contracts that provide general indemnifications. The Fund's maximum exposure under these arrangements is unknown as this would be dependent on future claims that may be made against the Fund. The risk of material loss from such claims is considered remote.

9. Other - continued

During the period, a transfer agent of the Fund, Fidelity Investments Institutional Operations Company, Inc. (FIIOC), an affiliate of Fidelity Management & Research Company, notified the Fund that the fund's books and records did not reflect a conversion of certain Class B to Class A shares upon their conversion date. Management has determined that this did not have a material impact to the Fund's reported net assets or results of operations in the accompanying financial statements. In March 2007, FIIOC converted the relevant Class B shares to Class A shares and recorded the conversion in the books and records of the Fund. FIIOC is in the process of determining appropriate remediation to affected shareholder accounts.

Chairman's Message

(photo_of_Edward_C_Johnson_3d)

Dear Shareholder:

Substantial single-day losses are not uncommon in the equity markets, and when they occur - as in late February - investors can be better served in the long term by buying good stocks at lower prices than by moving their money to the sidelines. While financial markets are always unpredictable, there are a number of time-tested principles that can put the historical odds in your favor.

One of the basic tenets is to invest for the long term. Over time, riding out the markets' inevitable ups and downs has proven much more effective than selling into panic or chasing the hottest trend. Even missing only a few of the markets' best days can significantly diminish investor returns. Patience also affords the benefits of compounding - of earning interest on additional income or reinvested dividends and capital gains. There are tax advantages and cost benefits to consider as well. The more you sell, the more taxes you pay, and the more you trade, the higher the costs. While staying the course doesn't eliminate risk, it can considerably lessen the effect of short-term declines.

You can further manage your investing risk through diversification. And today, more than ever, geographic diversification should be taken into account. Studies indicate that asset allocation is the single most important determinant of a portfolio's long-term success. The right mix of stocks, bonds and cash - aligned to your particular risk tolerance and investment objective - is very important. Age-appropriate rebalancing is also an essential aspect of asset allocation. For younger investors, an emphasis on equities - which historically have been the best performing asset class over time - is encouraged. As investors near their specific goal, such as retirement or sending a child to college, consideration may be given to replacing volatile assets (e.g. common stocks) with more-stable fixed investments (bonds or savings plans).

A third investment principle - investing regularly - can help lower the average cost of your purchases. Investing a certain amount of money each month or quarter helps ensure you won't pay for all your shares at market highs. This strategy - known as dollar cost averaging - also reduces unconstructive "emotion" from investing, helping shareholders avoid selling weak performers just prior to an upswing, or chasing a hot performer just before a correction.

We invite you to contact us via the Internet, through our Investor Centers or over the phone. It is our privilege to provide you the information you need to make the investments that are right for you.

Sincerely,

/s/Edward C. Johnson 3d

Edward C. Johnson 3d

Shareholder Expense Example

As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including sales charges (loads) on purchase payments or redemption proceeds, and (2) ongoing costs, including management fees, distribution and/or service (12b-1) fees and other Fund expenses. This Example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds.

The Example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period (September 1, 2006 to February 28, 2007).

Actual Expenses

The first line of the accompanying table for each class of the Fund provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000.00 (for example, an $8,600 account value divided by $1,000.00 = 8.6), then multiply the result by the number in the first line for a class of the Fund under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. In addition, the Fund, as a shareholder in the underlying Fidelity Central Funds, will indirectly bear its pro rata share of the fees and expenses incurred by the underlying Fidelity Central Funds. These fees and expenses are not included in the Fund's annualized expense ratio used to calculate the expense estimate in the table below.

Hypothetical Example for Comparison Purposes

The second line of the accompanying table for each class of the Fund provides information about hypothetical account values and hypothetical expenses based on a Class' actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Class' actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. In addition, the Fund, as a shareholder in the underlying Fidelity Central Funds, will indirectly bear its pro rata share of the fees and expenses incurred by the underlying Fidelity Central Funds. These fees and expenses are not included in the Fund's annualized expense ratio used to calculate the expense estimate in the table below.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transaction costs. Therefore, the second line of the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

Duration shows how much a bond fund's price fluctuates with changes in comparable interest rates. If rates rise 1%, for example, a fund with a five-year duration is likely to lose about 5% of its value. Other factors also can influence a bond fund's performance and share price. Accordingly, a bond fund's actual performance may differ from this example.

1. Organization.

Fidelity Advisor Mortgage Securities Fund (the Fund) is a fund of Fidelity Advisor Series II (the trust) and is authorized to issue an unlimited number of shares. The trust is registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company organized as a Massachusetts business trust. The Fund offers Class A, Class T, Class B, Class C, Fidelity Mortgage Securities Fund, and Institutional Class shares, each of which has equal rights as to assets and voting privileges. Each class has exclusive voting rights with respect to matters that affect that class. Class B shares will automatically convert to Class A shares after a holding period of seven years from the initial date of purchase. Investment income, realized and unrealized capital gains and losses, the common expenses of the Fund, and certain fund-level expense reductions, if any, are allocated on a pro rata basis to each class based on the relative net assets of each class to the total net assets of the Fund. Each class differs with respect to transfer agent and distribution and service plan fees incurred. Certain expense reductions also differ by class. The financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America, which require management to make certain estimates and assumptions at the date of the financial statements.

2. Investments in Fidelity Central Funds.

The Fund may invest in Fidelity Central Funds which are open-end investment companies available only to other investment companies and accounts managed by Fidelity Management & Research Company (FMR) and its affiliates. The Fund's Schedule of Investments lists each of the Fidelity Central Funds as an investment of the Fund but does not include the underlying holdings of each Fidelity Central Fund. As an Investing Fund, the Fund indirectly bears its proportionate share of the expenses of the underlying Fidelity Central Funds. A complete unaudited list of holdings for each Fidelity Central Fund is available upon request or, for the Fixed-Income Central Funds, at fidelity.com and/or advisor.fidelity.com, as applicable. The reports are located just after the Fund's financial statements and quarterly reports but are not part of the financial statements or quarterly reports. In addition, the financial statements of the Fidelity Central Funds, are available on the EDGAR Database on the SEC's web site, www.sec.gov, or upon request.

Based on their investment objective, each Fidelity Central Fund may invest or participate in various investment vehicles or strategies that are similar to those of the Fund. These strategies are consistent with the investment objectives of the Fund and may involve certain economic risks which may cause a decline in value of each of the Fidelity

3. Significant Accounting Policies.

The following summarizes the significant accounting policies of the Fund:

Security Valuation. Investments are valued and net asset value per share is calculated (NAV calculation) as of the close of business of the New York Stock Exchange, normally 4:00 p.m. Eastern time. Wherever possible, the Fund uses independent pricing services approved by the Board of Trustees to value its investments. Debt securities, including restricted securities, for which quotes are readily available, are valued by independent pricing services or by dealers who make markets in such securities. Pricing services consider yield or price of bonds of comparable quality, coupon, maturity and type as well as dealer supplied prices. When current market prices or quotations are not readily available or do not accurately reflect fair value, valuations may be determined in accordance with procedures adopted by the Board of Trustees. The frequency of when fair value pricing is used is unpredictable. The value of securities used for NAV calculation under fair value pricing may differ from published prices for the same securities. Investments in open-end mutual funds, including the Fidelity Central Funds, are valued at their closing net asset value each business day. Short-term securities with remaining maturities of sixty days or less for which quotations are not readily available are valued at amortized cost, which approximates value.

Investment Transactions and Income. For financial reporting purposes, the Fund's investment holdings and NAV include trades executed through the end of the last business day of the period. The NAV for processing shareholder transactions includes trades executed through the end of the prior business day. Gains and losses on securities sold are determined on the basis of identified cost. Interest income and income and capital gain distributions from the Fidelity Central Funds are accrued as earned, with

Investment Transactions and Income - continued

any distributions receivable as of period end included in Distributions receivable from Fidelity Central Funds on the Statement of Assets and Liabilities. Interest income includes coupon interest and amortization of premium and accretion of discount on debt securities.

Expenses. Most expenses of the trust can be directly attributed to a fund. Expenses which cannot be directly attributed are apportioned among each Fund in the trust. Expense estimates are accrued in the period to which they relate and adjustments are made when actual amounts are known.

Income Tax Information and Distributions to Shareholders. Each year, the Fund intends to qualify as a regulated investment company by distributing all of its taxable income and realized gains under Subchapter M of the Internal Revenue Code. As a result, no provision for income taxes is required in the accompanying financial statements.

Dividends are declared daily and paid monthly from net investment income. Distributions from realized gains, if any, are recorded on the ex-dividend date. Income dividends and capital gain distributions are declared separately for each class. Income and capital gain distributions are determined in accordance with income tax regulations, which may differ from generally accepted accounting principles.

Capital accounts within the financial statements are adjusted for permanent book-tax differences. These adjustments have no impact on net assets or the results of operations. Temporary book-tax differences will reverse in a subsequent period.

Book-tax differences are primarily due to prior period premium and discount on debt securities, market discount, deferred trustees compensation, financing transactions, capital loss carryforwards and losses deferred due to wash sales.

The federal tax cost of investments and unrealized appreciation (depreciation) as of period end were as follows:

New Accounting Pronouncements. In July 2006, Financial Accounting Standards Board Interpretation No. 48, Accounting for Uncertainty in Income Taxes - an interpretation of FASB Statement 109 (FIN 48), was issued and is effective on the last business day of the semiannual reporting period for fiscal years beginning after December 15,

Semiannual Report

(Amounts in thousands except ratios)

3. Significant Accounting Policies - continued

New Accounting Pronouncements - continued

2006. FIN 48 sets forth a threshold for financial statement recognition, measurement and disclosure of a tax position taken or expected to be taken on a tax return. Management is currently evaluating the impact, if any, the adoption of FIN 48 will have on the Fund's net assets, results of operations and financial statement disclosures.

In addition, in September 2006, Statement of Financial Accounting Standards No. 157, Fair Value Measurements (SFAS 157), was issued and is effective for fiscal years beginning after November 15, 2007. SFAS 157 defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. Management is currently evaluating the impact the adoption of SFAS 157 will have on the Fund's financial statement disclosures.

4. Operating Policies.

Repurchase Agreements. FMR has received an Exemptive Order from the Securities and Exchange Commission (the SEC) which permits the Fund and other affiliated entities of FMR to transfer uninvested cash balances into joint trading accounts which are then invested in repurchase agreements. The Fund may also invest directly with institutions in repurchase agreements. Repurchase agreements are collateralized by government or non-government securities. Upon settlement date, collateral is held in segregated accounts with custodian banks and may be obtained in the event of a default of the counterparty. The Fund monitors, on a daily basis, the value of the collateral to ensure it is at least equal to the principal amount of the repurchase agreement (including accrued interest). In the event of a default by the counterparty, realization of the collateral proceeds could be delayed, during which time the value of the collateral may decline.

Delayed Delivery Transactions and When-Issued Securities. The Fund may purchase or sell securities on a delayed delivery or when-issued basis. Payment and delivery may take place after the customary settlement period for that security. The price of the underlying securities and the date when the securities will be delivered and paid for are fixed at the time the transaction is negotiated. During the time a delayed delivery sell is outstanding, the contract is marked-to-market daily and equivalent deliverable securities are held for the transaction. The value of the securities purchased on a delayed delivery or when-issued basis are identified as such in the Fund's Schedule of Investments. The Fund may receive compensation for interest forgone in the purchase of a delayed delivery or when-issued security. With respect to purchase commitments, the

Semiannual Report

4. Operating Policies - continued

Delayed Delivery Transactions and When-Issued Securities - continued

Fund identifies securities as segregated in its records with a value at least equal to the amount of the commitment. Losses may arise due to changes in the value of the underlying securities or if the counterparty does not perform under the contract's terms, or if the issuer does not issue the securities due to political, economic, or other factors.

Restricted Securities. The Fund may invest in securities that are subject to legal or contractual restrictions on resale. These securities generally may be resold in transactions exempt from registration or to the public if the securities are registered. Disposal of these securities may involve time-consuming negotiations and expense, and prompt sale at an acceptable price may be difficult. Information regarding restricted securities is included at the end of the Fund's Schedule of Investments.

Swap Agreements. The Fund may invest in swaps for the purpose of managing its exposure to interest rate, credit or market risk.

Interest rate swaps are agreements to exchange cash flows periodically based on a notional principal amount, for example, the exchange of fixed rate interest payments for floating rate interest payments. Periodic payments received or made by the Fund are recorded in the accompanying Statement of Operations as realized gains or losses, respectively. The primary risk associated with interest rate swaps is that unfavorable changes in the fluctuation of interest rates could adversely impact a fund.

Total return swaps are agreements to exchange the return generated by one instrument or index for the return generated by another instrument, for example, the agreement to pay interest in exchange for a market-linked return based on a notional amount. To the extent the total return of the index exceeds the offsetting interest obligation, a fund will receive a payment from the counterparty. To the extent it is less, a fund will make a payment to the counterparty. Periodic payments received or made by the Fund are recorded in the accompanying Statement of Operations as realized gains or losses, respectively.

Credit default swaps involve the exchange of a fixed rate premium for protection against the loss in value of an underlying debt instrument in the event of a defined credit event (such as payment default or bankruptcy). Under the terms of the swap, one party acts as a "guarantor" receiving a periodic payment that is a fixed percentage applied to a notional principal amount. In return the party agrees to purchase the notional amount of the underlying instrument, at par, if a credit event occurs during the term of the swap. The Fund may enter into credit default swaps in which either it or its counterparty act as

Semiannual Report

Notes to Financial Statements (Unaudited) - continued

(Amounts in thousands except ratios)

4. Operating Policies - continued

Swap Agreements - continued

guarantors. By acting as the guarantor of a swap, a fund assumes the market and credit risk of the underlying instrument including liquidity and loss of value. Periodic payments and premiums received or made by the Fund are recorded in the accompanying Statement of Operations as realized gains or losses, respectively.

Swaps are marked-to-market daily based on dealer-supplied valuations and changes in value are recorded as unrealized appreciation (depreciation). Gains or losses are realized upon early termination of the swap agreement. Collateral, in the form of cash or securities, may be required to be held in segregated accounts with a fund's custodian in compliance with swap contracts. Risks may exceed amounts recognized on the Statement of Assets and Liabilities. These risks include changes in the returns of the underlying instruments, failure of the counterparties to perform under the contracts' terms and the possible lack of liquidity with respect to the swap agreements. Details of swap agreements open at period end are included in the Fund's Schedule of Investments under the caption "Swap Agreements."

Mortgage Dollar Rolls. To earn additional income, the Fund may employ trading strategies which involve the sale and simultaneous agreement to repurchase similar securities ("mortgage dollar rolls") or the purchase and simultaneous agreement to sell similar securities ("reverse mortgage dollar rolls"). The securities traded are mortgage securities and bear the same interest rate but may be collateralized by different pools of mortgages. During the period between the sale and repurchase in a mortgage dollar roll transaction, a fund will not be entitled to receive interest and principal payments on the securities sold but will invest the proceeds of the sale in other securities which may enhance the yield and total return. In addition, the difference between the sale price and the future purchase price is recorded as an adjustment to investment income. During the period between the purchase and subsequent sale in a reverse mortgage dollar roll transaction a fund is entitled to interest and principal payments on the securities purchased. The price differential between the purchase and sale is recorded as an adjustment to investment income. Losses may arise due to changes in the value of the securities or if the counterparty does not perform under the terms of the agreement. If the counterparty files for bankruptcy or becomes insolvent, a fund's right to repurchase or sell securities may be limited.

5. Purchases and Sales of Investments.

Purchases and sales of securities (including the Fixed-Income Central Funds), other than short-term securities and U.S. government securities, aggregated $467,402 and $286,584, respectively.

Semiannual Report

6. Fees and Other Transactions with Affiliates.

Management Fee. FMR and its affiliates provide the Fund with investment management related services for which the Fund pays a monthly management fee. The management fee is the sum of an individual fund fee rate that is based on an annual rate of .20% of the Fund's average net assets and a group fee rate that averaged .12% during the period. The group fee rate is based upon the average net assets of all the mutual funds advised by FMR. The group fee rate decreases as assets under management increase and increases as assets under management decrease. For the period, the total annualized management fee rate was .32% of the Fund's average net assets.

Distribution and Service Plan. In accordance with Rule 12b-1 of the 1940 Act, the Fund has adopted separate Distribution and Service Plans for each class of shares. Certain classes pay Fidelity Distributors Corporation (FDC), an affiliate of FMR, separate Distribution and Service Fees, each of which is based on an annual percentage of each class' average net assets. In addition, FDC may pay financial intermediaries for selling shares of the Fund and providing shareholder support services. For the period, the Distribution and Service Fee rates and the total amounts paid to and retained by FDC were as follows:

On January 18, 2007, the Board of Trustees approved an increase in Class A's Service fee from .15% to .25%, effective April 1, 2007.

Sales Load. FDC receives a front-end sales charge of up to 4.75% for selling Class A shares, and 3.50% for selling Class T shares, some of which is paid to financial intermediaries for selling shares of the Fund. FDC receives the proceeds of contingent deferred sales charges levied on Class A, Class T, Class B, and Class C redemptions. These charges depend on the holding period. The deferred sales charges range from 5% to 1% for Class B, 1% for Class C, .75% to .50% for certain purchases of Class A shares and .25% for certain purchases of Class T shares.

On January 18, 2007, the Board of Trustees approved a change in Class A and Class T's front-end sales charge. Effective April 1, 2007, FDC will receive a front-end sales charge of up to 4.00% for selling Class A and Class T shares.

Transfer Agent Fees. Fidelity Investments Institutional Operations Company, Inc. (FIIOC), an affiliate of FMR, is the transfer, dividend disbursing and shareholder servicing agent for each class of the Fund, except for Fidelity Mortgage Securities Fund. Fidelity Service Company, Inc. (FSC), an affiliate of FMR, is the transfer agent for Fidelity Mortgage Securities Fund shares. FIIOC receives account fees and asset-based fees that vary according to the account size and type of account of the shareholders of the respective classes of the Fund. FSC receives an asset-based fee of .10% of Fidelity Mortgage Securities Fund's average net assets. FIIOC and FSC pay for typesetting, printing and mailing of shareholder reports, except proxy statements. For the period, the total transfer agent fees paid by each class to FIIOC or FSC, were as follows:

Fundwide Operations Fee. Pursuant to the Fundwide Operations and Expense Agreement (FWOE), FMR has agreed to provide for fund level expenses (which do not include transfer agent, Rule 12b-1 fees, compensation of the independent trustees, interest (including commitment fees), taxes or extraordinary expenses, if any) in return

Semiannual Report

Fundwide Operations Fee - continued

for a FWOE fee equal to .35% less the total amount of the management fee. The FWOE paid by the Fund is reduced by an amount equal to the fees and expenses paid to the independent trustees. For the period, the FWOE fee was equivalent to an annualized rate of .03% of average net assets.

7. Committed Line of Credit.

The Fund participates with other funds managed by FMR in a $4.2 billion credit facility (the "line of credit") to be utilized for temporary or emergency purposes to fund shareholder redemptions or for other short-term liquidity purposes. The Fund has agreed to pay commitment fees on its pro rata portion of the line of credit, which amounted to $2 and is reflected in Miscellaneous Expense on the Statement of Operations. During the period, there were no borrowings on this line of credit.

8. Expense Reductions.

Through arrangements with the Fund's custodian and each class' transfer agent, credits realized as a result of uninvested cash balances were used to reduce the Fund's expenses. During the period, these credits reduced the Fund's management fee by $3. During the period, credits reduced each class' transfer agent expense as noted in the table below.

9. Other.

The Fund's organizational documents provide former and current trustees and officers with a limited indemnification against liabilities arising in connection with the performance of their duties to the Fund. In the normal course of business, the Fund may also enter into contracts that provide general indemnifications. The Fund's maximum exposure under these arrangements is unknown as this would be dependent on future claims that may be made against the Fund. The risk of material loss from such claims is considered remote.

During the period, a transfer agent of the Fund, Fidelity Investments Institutional Operations Company, Inc. (FIIOC), an affiliate of Fidelity Management & Research Company, notified the Fund that the fund's books and records did not reflect a conversion of certain Class B to Class A shares upon their conversion date. Management has determined that this did not have a material impact to the Fund's reported net assets or results of operations in the accompanying financial statements. In March 2007, FIIOC converted the relevant Class B shares to Class A shares and recorded the conversion in the books and records of the Fund. FIIOC is in the process of determining appropriate remediation to affected shareholder accounts.

Chairman's Message

(photo_of_Edward_C_Johnson_3d)

Dear Shareholder:

Substantial single-day losses are not uncommon in the equity markets, and when they occur - as in late February - investors can be better served in the long term by buying good stocks at lower prices than by moving their money to the sidelines. While financial markets are always unpredictable, there are a number of time-tested principles that can put the historical odds in your favor.

One of the basic tenets is to invest for the long term. Over time, riding out the markets' inevitable ups and downs has proven much more effective than selling into panic or chasing the hottest trend. Even missing only a few of the markets' best days can significantly diminish investor returns. Patience also affords the benefits of compounding - of earning interest on additional income or reinvested dividends and capital gains. There are tax advantages and cost benefits to consider as well. The more you sell, the more taxes you pay, and the more you trade, the higher the costs. While staying the course doesn't eliminate risk, it can considerably lessen the effect of short-term declines.

You can further manage your investing risk through diversification. And today, more than ever, geographic diversification should be taken into account. Studies indicate that asset allocation is the single most important determinant of a portfolio's long-term success. The right mix of stocks, bonds and cash - aligned to your particular risk tolerance and investment objective - is very important. Age-appropriate rebalancing is also an essential aspect of asset allocation. For younger investors, an emphasis on equities - which historically have been the best performing asset class over time - is encouraged. As investors near their specific goal, such as retirement or sending a child to college, consideration may be given to replacing volatile assets (e.g. common stocks) with more-stable fixed investments (bonds or savings plans).

A third investment principle - investing regularly - can help lower the average cost of your purchases. Investing a certain amount of money each month or quarter helps ensure you won't pay for all your shares at market highs. This strategy - known as dollar cost averaging - also reduces unconstructive "emotion" from investing, helping shareholders avoid selling weak performers just prior to an upswing, or chasing a hot performer just before a correction.

We invite you to contact us via the Internet, through our Investor Centers or over the phone. It is our privilege to provide you the information you need to make the investments that are right for you.

Sincerely,

/s/Edward C. Johnson 3d

Shareholder Expense Example

As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including sales charges (loads) on purchase payments or redemption proceeds, and (2) ongoing costs, including management fees, distribution and/or service (12b-1) fees and other Fund expenses. This Example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds.

The Example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period (September 1, 2006 to February 28, 2007).

Actual Expenses

The first line of the accompanying table for each class of the Fund provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000.00 (for example, an $8,600 account value divided by $1,000.00 = 8.6), then multiply the result by the number in the first line for a class of the Fund under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. In addition, the Fund, as a shareholder in the underlying Fidelity Central Funds, will indirectly bear its pro rata share of the fees and expenses incurred by the underlying Fidelity Central Funds. These fees and expenses are not included in the Fund's annualized expense ratio used to calculate the expense estimate in the table below.

Hypothetical Example for Comparison Purposes

The second line of the accompanying table for each class of the Fund provides information about hypothetical account values and hypothetical expenses based on a Class' actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Class' actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. In addition, the Fund, as a shareholder in the underlying Fidelity Central Funds, will indirectly bear its pro rata share of the fees and expenses incurred by the underlying Fidelity Central Funds. These fees and expenses are not included in the Fund's annualized expense ratio used to calculate the expense estimate in the table below.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transaction costs. Therefore, the second line of the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

Duration shows how much a bond fund's price fluctuates with changes in comparable interest rates. If rates rise 1%, for example, a fund with a five-year duration is likely to lose about 5% of its value. Other factors also can influence a bond fund's performance and share price. Accordingly, a bond fund's actual performance may differ from this example.

1. Organization.

Fidelity Advisor Mortgage Securities Fund (the Fund) is a fund of Fidelity Advisor Series II (the trust) and is authorized to issue an unlimited number of shares. The trust is registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company organized as a Massachusetts business trust. The Fund offers Class A, Class T, Class B, Class C, Fidelity Mortgage Securities Fund, and Institutional Class shares, each of which has equal rights as to assets and voting privileges. Each class has exclusive voting rights with respect to matters that affect that class. Class B shares will automatically convert to Class A shares after a holding period of seven years from the initial date of purchase. Investment income, realized and unrealized capital gains and losses, the common expenses of the Fund, and certain fund-level expense reductions, if any, are allocated on a pro rata basis to each class based on the relative net assets of each class to the total net assets of the Fund. Each class differs with respect to transfer agent and distribution and service plan fees incurred. Certain expense reductions also differ by class. The financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America, which require management to make certain estimates and assumptions at the date of the financial statements.

2. Investments in Fidelity Central Funds.

The Fund may invest in Fidelity Central Funds which are open-end investment companies available only to other investment companies and accounts managed by Fidelity Management & Research Company (FMR) and its affiliates. The Fund's Schedule of Investments lists each of the Fidelity Central Funds as an investment of the Fund but does not include the underlying holdings of each Fidelity Central Fund. As an Investing Fund, the Fund indirectly bears its proportionate share of the expenses of the underlying Fidelity Central Funds. A complete unaudited list of holdings for each Fidelity Central Fund is available upon request or, for the Fixed-Income Central Funds, at fidelity.com and/or advisor.fidelity.com, as applicable. The reports are located just after the Fund's financial statements and quarterly reports but are not part of the financial statements or quarterly reports. In addition, the financial statements of the Fidelity Central Funds, are available on the EDGAR Database on the SEC's web site, www.sec.gov, or upon request.

Based on their investment objective, each Fidelity Central Fund may invest or participate in various investment vehicles or strategies that are similar to those of the Fund. These strategies are consistent with the investment objectives of the Fund and may involve certain economic risks which may cause a decline in value of each of the Fidelity

3. Significant Accounting Policies.

The following summarizes the significant accounting policies of the Fund:

Security Valuation. Investments are valued and net asset value per share is calculated (NAV calculation) as of the close of business of the New York Stock Exchange, normally 4:00 p.m. Eastern time. Wherever possible, the Fund uses independent pricing services approved by the Board of Trustees to value its investments. Debt securities, including restricted securities, for which quotes are readily available, are valued by independent pricing services or by dealers who make markets in such securities. Pricing services consider yield or price of bonds of comparable quality, coupon, maturity and type as well as dealer supplied prices. When current market prices or quotations are not readily available or do not accurately reflect fair value, valuations may be determined in accordance with procedures adopted by the Board of Trustees. The frequency of when fair value pricing is used is unpredictable. The value of securities used for NAV calculation under fair value pricing may differ from published prices for the same securities. Investments in open-end mutual funds, including the Fidelity Central Funds, are valued at their closing net asset value each business day. Short-term securities with remaining maturities of sixty days or less for which quotations are not readily available are valued at amortized cost, which approximates value.

Investment Transactions and Income. For financial reporting purposes, the Fund's investment holdings and NAV include trades executed through the end of the last business day of the period. The NAV for processing shareholder transactions includes trades executed through the end of the prior business day. Gains and losses on securities sold are determined on the basis of identified cost. Interest income and income and capital gain distributions from the Fidelity Central Funds are accrued as earned, with

Investment Transactions and Income - continued

any distributions receivable as of period end included in Distributions receivable from Fidelity Central Funds on the Statement of Assets and Liabilities. Interest income includes coupon interest and amortization of premium and accretion of discount on debt securities.

Expenses. Most expenses of the trust can be directly attributed to a fund. Expenses which cannot be directly attributed are apportioned among each Fund in the trust. Expense estimates are accrued in the period to which they relate and adjustments are made when actual amounts are known.

Income Tax Information and Distributions to Shareholders. Each year, the Fund intends to qualify as a regulated investment company by distributing all of its taxable income and realized gains under Subchapter M of the Internal Revenue Code. As a result, no provision for income taxes is required in the accompanying financial statements.

Dividends are declared daily and paid monthly from net investment income. Distributions from realized gains, if any, are recorded on the ex-dividend date. Income dividends and capital gain distributions are declared separately for each class. Income and capital gain distributions are determined in accordance with income tax regulations, which may differ from generally accepted accounting principles.

Capital accounts within the financial statements are adjusted for permanent book-tax differences. These adjustments have no impact on net assets or the results of operations. Temporary book-tax differences will reverse in a subsequent period.

Book-tax differences are primarily due to prior period premium and discount on debt securities, market discount, deferred trustees compensation, financing transactions, capital loss carryforwards and losses deferred due to wash sales.

The federal tax cost of investments and unrealized appreciation (depreciation) as of period end were as follows:

New Accounting Pronouncements. In July 2006, Financial Accounting Standards Board Interpretation No. 48, Accounting for Uncertainty in Income Taxes - an interpretation of FASB Statement 109 (FIN 48), was issued and is effective on the last business day of the semiannual reporting period for fiscal years beginning after December 15,

(Amounts in thousands except ratios)

3. Significant Accounting Policies - continued

New Accounting Pronouncements - continued

2006. FIN 48 sets forth a threshold for financial statement recognition, measurement and disclosure of a tax position taken or expected to be taken on a tax return. Management is currently evaluating the impact, if any, the adoption of FIN 48 will have on the Fund's net assets, results of operations and financial statement disclosures.

In addition, in September 2006, Statement of Financial Accounting Standards No. 157, Fair Value Measurements (SFAS 157), was issued and is effective for fiscal years beginning after November 15, 2007. SFAS 157 defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. Management is currently evaluating the impact the adoption of SFAS 157 will have on the Fund's financial statement disclosures.

4. Operating Policies.

Repurchase Agreements. FMR has received an Exemptive Order from the Securities and Exchange Commission (the SEC) which permits the Fund and other affiliated entities of FMR to transfer uninvested cash balances into joint trading accounts which are then invested in repurchase agreements. The Fund may also invest directly with institutions in repurchase agreements. Repurchase agreements are collateralized by government or non-government securities. Upon settlement date, collateral is held in segregated accounts with custodian banks and may be obtained in the event of a default of the counterparty. The Fund monitors, on a daily basis, the value of the collateral to ensure it is at least equal to the principal amount of the repurchase agreement (including accrued interest). In the event of a default by the counterparty, realization of the collateral proceeds could be delayed, during which time the value of the collateral may decline.

Delayed Delivery Transactions and When-Issued Securities. The Fund may purchase or sell securities on a delayed delivery or when-issued basis. Payment and delivery may take place after the customary settlement period for that security. The price of the underlying securities and the date when the securities will be delivered and paid for are fixed at the time the transaction is negotiated. During the time a delayed delivery sell is outstanding, the contract is marked-to-market daily and equivalent deliverable securities are held for the transaction. The value of the securities purchased on a delayed delivery or when-issued basis are identified as such in the Fund's Schedule of Investments. The Fund may receive compensation for interest forgone in the purchase of a delayed delivery or when-issued security. With respect to purchase commitments, the

Semiannual Report

4. Operating Policies - continued

Delayed Delivery Transactions and When-Issued Securities - continued

Fund identifies securities as segregated in its records with a value at least equal to the amount of the commitment. Losses may arise due to changes in the value of the underlying securities or if the counterparty does not perform under the contract's terms, or if the issuer does not issue the securities due to political, economic, or other factors.

Restricted Securities. The Fund may invest in securities that are subject to legal or contractual restrictions on resale. These securities generally may be resold in transactions exempt from registration or to the public if the securities are registered. Disposal of these securities may involve time-consuming negotiations and expense, and prompt sale at an acceptable price may be difficult. Information regarding restricted securities is included at the end of the Fund's Schedule of Investments.

Swap Agreements. The Fund may invest in swaps for the purpose of managing its exposure to interest rate, credit or market risk.

Interest rate swaps are agreements to exchange cash flows periodically based on a notional principal amount, for example, the exchange of fixed rate interest payments for floating rate interest payments. Periodic payments received or made by the Fund are recorded in the accompanying Statement of Operations as realized gains or losses, respectively. The primary risk associated with interest rate swaps is that unfavorable changes in the fluctuation of interest rates could adversely impact a fund.

Total return swaps are agreements to exchange the return generated by one instrument or index for the return generated by another instrument, for example, the agreement to pay interest in exchange for a market-linked return based on a notional amount. To the extent the total return of the index exceeds the offsetting interest obligation, a fund will receive a payment from the counterparty. To the extent it is less, a fund will make a payment to the counterparty. Periodic payments received or made by the Fund are recorded in the accompanying Statement of Operations as realized gains or losses, respectively.

Credit default swaps involve the exchange of a fixed rate premium for protection against the loss in value of an underlying debt instrument in the event of a defined credit event (such as payment default or bankruptcy). Under the terms of the swap, one party acts as a "guarantor" receiving a periodic payment that is a fixed percentage applied to a notional principal amount. In return the party agrees to purchase the notional amount of the underlying instrument, at par, if a credit event occurs during the term of the swap. The Fund may enter into credit default swaps in which either it or its counterparty act as

Semiannual Report

Notes to Financial Statements (Unaudited) - continued

(Amounts in thousands except ratios)

4. Operating Policies - continued

Swap Agreements - continued

guarantors. By acting as the guarantor of a swap, a fund assumes the market and credit risk of the underlying instrument including liquidity and loss of value. Periodic payments and premiums received or made by the Fund are recorded in the accompanying Statement of Operations as realized gains or losses, respectively.

Swaps are marked-to-market daily based on dealer-supplied valuations and changes in value are recorded as unrealized appreciation (depreciation). Gains or losses are realized upon early termination of the swap agreement. Collateral, in the form of cash or securities, may be required to be held in segregated accounts with a fund's custodian in compliance with swap contracts. Risks may exceed amounts recognized on the Statement of Assets and Liabilities. These risks include changes in the returns of the underlying instruments, failure of the counterparties to perform under the contracts' terms and the possible lack of liquidity with respect to the swap agreements. Details of swap agreements open at period end are included in the Fund's Schedule of Investments under the caption "Swap Agreements."

Mortgage Dollar Rolls. To earn additional income, the Fund may employ trading strategies which involve the sale and simultaneous agreement to repurchase similar securities ("mortgage dollar rolls") or the purchase and simultaneous agreement to sell similar securities ("reverse mortgage dollar rolls"). The securities traded are mortgage securities and bear the same interest rate but may be collateralized by different pools of mortgages. During the period between the sale and repurchase in a mortgage dollar roll transaction, a fund will not be entitled to receive interest and principal payments on the securities sold but will invest the proceeds of the sale in other securities which may enhance the yield and total return. In addition, the difference between the sale price and the future purchase price is recorded as an adjustment to investment income. During the period between the purchase and subsequent sale in a reverse mortgage dollar roll transaction a fund is entitled to interest and principal payments on the securities purchased. The price differential between the purchase and sale is recorded as an adjustment to investment income. Losses may arise due to changes in the value of the securities or if the counterparty does not perform under the terms of the agreement. If the counterparty files for bankruptcy or becomes insolvent, a fund's right to repurchase or sell securities may be limited.

5. Purchases and Sales of Investments.

Purchases and sales of securities (including the Fixed-Income Central Funds), other than short-term securities and U.S. government securities, aggregated $467,402 and $286,584, respectively.

Semiannual Report

6. Fees and Other Transactions with Affiliates.

Management Fee. FMR and its affiliates provide the Fund with investment management related services for which the Fund pays a monthly management fee. The management fee is the sum of an individual fund fee rate that is based on an annual rate of .20% of the Fund's average net assets and a group fee rate that averaged .12% during the period. The group fee rate is based upon the average net assets of all the mutual funds advised by FMR. The group fee rate decreases as assets under management increase and increases as assets under management decrease. For the period, the total annualized management fee rate was .32% of the Fund's average net assets.

Distribution and Service Plan. In accordance with Rule 12b-1 of the 1940 Act, the Fund has adopted separate Distribution and Service Plans for each class of shares. Certain classes pay Fidelity Distributors Corporation (FDC), an affiliate of FMR, separate Distribution and Service Fees, each of which is based on an annual percentage of each class' average net assets. In addition, FDC may pay financial intermediaries for selling shares of the Fund and providing shareholder support services. For the period, the Distribution and Service Fee rates and the total amounts paid to and retained by FDC were as follows:

On January 18, 2007, the Board of Trustees approved an increase in Class A's Service fee from .15% to .25%, effective April 1, 2007.

Sales Load. FDC receives a front-end sales charge of up to 4.75% for selling Class A shares, and 3.50% for selling Class T shares, some of which is paid to financial intermediaries for selling shares of the Fund. FDC receives the proceeds of contingent deferred sales charges levied on Class A, Class T, Class B, and Class C redemptions. These charges depend on the holding period. The deferred sales charges range from 5% to 1% for Class B, 1% for Class C, .75% to .50% for certain purchases of Class A shares and .25% for certain purchases of Class T shares.

On January 18, 2007, the Board of Trustees approved a change in Class A and Class T's front-end sales charge. Effective April 1, 2007, FDC will receive a front-end sales charge of up to 4.00% for selling Class A and Class T shares.

Transfer Agent Fees. Fidelity Investments Institutional Operations Company, Inc. (FIIOC), an affiliate of FMR, is the transfer, dividend disbursing and shareholder servicing agent for each class of the Fund, except for Fidelity Mortgage Securities Fund. Fidelity Service Company, Inc. (FSC), an affiliate of FMR, is the transfer agent for Fidelity Mortgage Securities Fund shares. FIIOC receives account fees and asset-based fees that vary according to the account size and type of account of the shareholders of the respective classes of the Fund. FSC receives an asset-based fee of .10% of Fidelity Mortgage Securities Fund's average net assets. FIIOC and FSC pay for typesetting, printing and mailing of shareholder reports, except proxy statements. For the period, the total transfer agent fees paid by each class to FIIOC or FSC, were as follows:

Semiannual Report

Fundwide Operations Fee - continued

for a FWOE fee equal to .35% less the total amount of the management fee. The FWOE paid by the Fund is reduced by an amount equal to the fees and expenses paid to the independent trustees. For the period, the FWOE fee was equivalent to an annualized rate of .03% of average net assets.

7. Committed Line of Credit.

The Fund participates with other funds managed by FMR in a $4.2 billion credit facility (the "line of credit") to be utilized for temporary or emergency purposes to fund shareholder redemptions or for other short-term liquidity purposes. The Fund has agreed to pay commitment fees on its pro rata portion of the line of credit, which amounted to $2 and is reflected in Miscellaneous Expense on the Statement of Operations. During the period, there were no borrowings on this line of credit.

8. Expense Reductions.

Through arrangements with the Fund's custodian and each class' transfer agent, credits realized as a result of uninvested cash balances were used to reduce the Fund's expenses. During the period, these credits reduced the Fund's management fee by $3. During the period, credits reduced each class' transfer agent expense as noted in the table below.

9. Other.

The Fund's organizational documents provide former and current trustees and officers with a limited indemnification against liabilities arising in connection with the performance of their duties to the Fund. In the normal course of business, the Fund may also enter into contracts that provide general indemnifications. The Fund's maximum exposure under these arrangements is unknown as this would be dependent on future claims that may be made against the Fund. The risk of material loss from such claims is considered remote.

During the period, a transfer agent of the Fund, Fidelity Investments Institutional Operations Company, Inc. (FIIOC), an affiliate of Fidelity Management & Research Company, notified the Fund that the fund's books and records did not reflect a conversion of certain Class B to Class A shares upon their conversion date. Management has determined that this did not have a material impact to the Fund's reported net assets or results of operations in the accompanying financial statements. In March 2007, FIIOC converted the relevant Class B shares to Class A shares and recorded the conversion in the books and records of the Fund. FIIOC is in the process of determining appropriate remediation to affected shareholder accounts.

Semiannual Report

Notes to Shareholders:

As discussed in prior shareholder reports, the fund changed its investment approach in the way it invests in the investment-grade debt market, seeking exposure to various types of securities by investing in central funds as well as investing directly in individual investment-grade securities. Central funds are Fidelity mutual funds used by this fund and other Fidelity funds as an investment vehicle to gain pooled exposure to a particular core market sector, such as corporate bonds or mortgage-backed securities. Instead of multiple funds each investing in investment-grade debt securities individually, they can now take advantage of consolidating investments in a single, larger pool of investment-grade debt by investing directly in central funds. Shares of the central funds are offered only to other Fidelity mutual funds and accounts; investors cannot directly invest in them.

It's important to point out that investing in central funds does not impact the fund's investment objective or risk profile, only the mechanics of how we manage its investment portfolio. The portfolio managers continue to be responsible for choosing appropriate investments for their funds, whether they elect to purchase shares of a central fund or individual securities. Fidelity does not charge any additional management fees for central funds.

Investing in central funds does change the way this report presents the fund's holdings. The Investments section continues to list direct investments of the fund, including each central fund. However, many of the individual investment-grade debt securities previously held by the fund were transferred to the central funds, so they are no longer directly held and thus not listed. Information on the underlying holdings of the fixed-income central funds is available at advisor.fidelity.com, and the financial statements are available upon request.

Chairman's Message

(photo_of_Edward_C_Johnson_3d)

Dear Shareholder:

Substantial single-day losses are not uncommon in the equity markets, and when they occur - as in late February - investors can be better served in the long term by buying good stocks at lower prices than by moving their money to the sidelines. While financial markets are always unpredictable, there are a number of time-tested principles that can put the historical odds in your favor.

One of the basic tenets is to invest for the long term. Over time, riding out the markets' inevitable ups and downs has proven much more effective than selling into panic or chasing the hottest trend. Even missing only a few of the markets' best days can significantly diminish investor returns. Patience also affords the benefits of compounding - of earning interest on additional income or reinvested dividends and capital gains. There are tax advantages and cost benefits to consider as well. The more you sell, the more taxes you pay, and the more you trade, the higher the costs. While staying the course doesn't eliminate risk, it can considerably lessen the effect of short-term declines.

You can further manage your investing risk through diversification. And today, more than ever, geographic diversification should be taken into account. Studies indicate that asset allocation is the single most important determinant of a portfolio's long-term success. The right mix of stocks, bonds and cash - aligned to your particular risk tolerance and investment objective - is very important. Age-appropriate rebalancing is also an essential aspect of asset allocation. For younger investors, an emphasis on equities - which historically have been the best performing asset class over time - is encouraged. As investors near their specific goal, such as retirement or sending a child to college, consideration may be given to replacing volatile assets (e.g. common stocks) with more-stable fixed investments (bonds or savings plans).

A third investment principle - investing regularly - can help lower the average cost of your purchases. Investing a certain amount of money each month or quarter helps ensure you won't pay for all your shares at market highs. This strategy - known as dollar cost averaging - also reduces unconstructive "emotion" from investing, helping shareholders avoid selling weak performers just prior to an upswing, or chasing a hot performer just before a correction.

We invite you to contact us via the Internet, through our Investor Centers or over the phone. It is our privilege to provide you the information you need to make the investments that are right for you.

Sincerely,

/s/Edward C. Johnson 3d

Semiannual Report

Shareholder Expense Example

As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including sales charges (loads) on purchase payments or redemption proceeds, and (2) ongoing costs, including management fees, distribution and/or service (12b-1) fees and other Fund expenses. This Example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds.

The Example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period (September 1, 2006 to February 28, 2007).

Actual Expenses

The first line of the accompanying table for each class of the Fund provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000.00 (for example, an $8,600 account value divided by $1,000.00 = 8.6), then multiply the result by the number in the first line for a class of the Fund under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. In addition, the Fund, as a shareholder in the underlying Fidelity Central Funds, will indirectly bear its pro rata share of the fees and expenses incurred by the underlying Fidelity Central Funds. These fees and expenses are not included in the Fund's annualized expense ratio used to calculate the expense estimate in the table below.

Hypothetical Example for Comparison Purposes

The second line of the accompanying table for each class of the Fund provides information about hypothetical account values and hypothetical expenses based on a Class' actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Class' actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. In addition, the Fund, as a shareholder in the underlying Fidelity Central Funds, will indirectly bear its pro rata share of the fees and expenses incurred by the underlying Fidelity Central Funds. These fees and expenses are not included in the Fund's annualized expense ratio used to calculate the expense estimate in the table below.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transaction costs. Therefore, the second line of the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

Duration shows how much a bond fund's price fluctuates with changes in comparable interest rates. If rates rise 1%, for example, a fund with a five-year duration is likely to lose about 5% of its value. Other factors also can influence a bond fund's performance and share price. Accordingly, a bond fund's actual performance may differ from this example.

Semiannual Report

Notes to Financial Statements

For the period ended February 28, 2007

1. Organization.

Fidelity Advisor Short Fixed-Income Fund (the Fund) is a fund of Fidelity Advisor Series II (the trust) and is authorized to issue an unlimited number of shares. The trust is registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company organized as a Massachusetts business trust. The Fund offers Class A, Class T, Class B, Class C, and Institutional Class shares, each of which has equal rights as to assets and voting privileges. Each class has exclusive voting rights with respect to matters that affect that class. Class B shares will automatically convert to Class A shares after a holding period of four years from the initial date of purchase. Investment income, realized and unrealized capital gains and losses, the common expenses of the Fund, and certain fund-level expense reductions, if any, are allocated on a pro rata basis to each class based on the relative net assets of each class to the total net assets of the Fund. Each class differs with respect to transfer agent and distribution and service plan fees incurred. Certain expense reductions also differ by class. The financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America, which require management to make certain estimates and assumptions at the date of the financial statements.

2. Investments in Fidelity Central Funds.

The Fund may invest in Fidelity Central Funds which are open-end investment companies available only to other investment companies and accounts managed by Fidelity Management & Research Company (FMR) and its affiliates. The Fund's Schedule of Investments lists each of the Fidelity Central Funds as an investment of the Fund but does not include the underlying holdings of each Fidelity Central Fund. As an Investing Fund, the Fund indirectly bears its proportionate share of the expenses of the underlying Fidelity Central Funds. A complete unaudited list of holdings for each Fidelity Central Fund is available upon request or, for the Fixed-Income Central Funds, at advisor.fidelity.com. The reports are located just after the Fund's financial statements and quarterly reports but are not part of the financial statements or quarterly reports. In addition, the financial statements of the Fidelity Central Funds, which are not covered by the Fund's Report of Independent Registered Public Accounting Firm, are available on the EDGAR Database on the SEC's web site, www.sec.gov, or upon request.

Based on their investment objective, each Fidelity Central Fund may invest or participate in various investment vehicles or strategies that are similar to those of the Fund. These strategies are consistent with the investment objectives of the Fund and may involve certain economic risks which may cause a decline in value of each of the Fidelity

3. Significant Accounting Policies.

The following summarizes the significant accounting policies of the Fund:

Security Valuation. Investments are valued and net asset value per share is calculated (NAV calculation) as of the close of business of the New York Stock Exchange, normally 4:00 p.m. Eastern time. Wherever possible, the Fund uses independent pricing services approved by the Board of Trustees to value its investments. Debt securities, including restricted securities, for which quotations are readily available, are valued by independent pricing services or by dealers who make markets in such securities. Pricing services consider yield or price of bonds of comparable quality, coupon, maturity and type as well as dealer supplied prices.

When current market prices or quotations are not readily available or do not accurately reflect fair value, valuations may be determined in accordance with procedures adopted

Semiannual Report

Notes to Financial Statements - continued

3. Significant Accounting Policies - continued

Security Valuation - continued

by the Board of Trustees. The frequency of when fair value pricing is used is unpredictable. The value of securities used for NAV calculation under fair value pricing may differ from published prices for the same securities. Investments in open-end mutual funds, including the Fidelity Central Funds, are valued at their closing net asset value each business day. Short-term securities with remaining maturities of sixty days or less for which quotations are not readily available are valued at amortized cost, which approximates value.

Investment Transactions and Income. For financial reporting purposes, the Fund's investment holdings and NAV include trades executed through the end of the last business day of the period. The NAV for processing shareholder transactions includes trades executed through the end of the prior business day. Gains and losses on securities sold are determined on the basis of identified cost and may include proceeds received from litigation. Dividend income is recorded on the ex-dividend date. Interest income and income and capital gain distributions from the Fidelity Central Funds are accrued as earned, with any distributions receivable as of period end included in Distributions receivable from Fidelity Central Funds on the Statement of Assets and Liabilities. Interest income includes coupon interest and amortization of premium and accretion of discount on debt securities.

Expenses. Most expenses of the trust can be directly attributed to a fund. Expenses which cannot be directly attributed are apportioned among each Fund in the trust. Expense estimates are accrued in the period to which they relate and adjustments are made when actual amounts are known.

Income Tax Information and Distributions to Shareholders. Each year, the Fund intends to qualify as a regulated investment company by distributing all of its taxable income and realized gains under Subchapter M of the Internal Revenue Code. As a result, no provision for income taxes is required in the accompanying financial statements.

Dividends are declared daily and paid monthly from net investment income. Distributions from realized gains, if any, are recorded on the ex-dividend date. Income dividends and capital gain distributions are declared separately for each class. Income and capital gain distributions are determined in accordance with income tax regulations, which may differ from generally accepted accounting principles.

Capital accounts within the financial statements are adjusted for permanent book-tax differences. These adjustments have no impact on net assets or the results of operations. Temporary book-tax differences will reverse in a subsequent period.

Semiannual Report

3. Significant Accounting Policies - continued

Income Tax Information and Distributions to Shareholders - continued

Book-tax differences are primarily due to futures transactions, swap agreements, prior period premium and discount on debt securities, market discount, deferred trustees compensation, financing transactions, capital loss carryforwards, and losses deferred due to wash sales.

The federal tax cost of investments and unrealized appreciation (depreciation) as of period end were as follows:

Unrealized appreciation

$ 5,997,014

Unrealized depreciation

(5,938,669)

Net unrealized appreciation (depreciation)

$ 58,345

Cost for federal income tax purposes

$ 1,367,716,571

New Accounting Pronouncements. In July 2006, Financial Accounting Standards Board Interpretation No. 48, Accounting for Uncertainty in Income Taxes - an interpretation of FASB Statement 109 (FIN 48), was issued and is effective on the last business day of the semiannual reporting period for fiscal years beginning after December 15, 2006. FIN 48 sets forth a threshold for financial statement recognition, measurement and disclosure of a tax position taken or expected to be taken on a tax return. Management is currently evaluating the impact, if any, the adoption of FIN 48 will have on the Fund's net assets, results of operations and financial statement disclosures.

In addition, in September 2006, Statement of Financial Accounting Standards No. 157, Fair Value Measurements (SFAS 157), was issued and is effective for fiscal years beginning after November 15, 2007. SFAS 157 defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. Management is currently evaluating the impact the adoption of SFAS 157 will have on the Fund's financial statement disclosures.

4. Operating Policies.

Repurchase Agreements. FMR has received an Exemptive Order from the Securities and Exchange Commission (the SEC) which permits the Fund and other affiliated entities of FMR to transfer uninvested cash balances into joint trading accounts which are then invested in repurchase agreements. The Fund may also invest directly with institutions in repurchase agreements. Repurchase agreements are collateralized by government or non-government securities. Upon settlement date, collateral is held in segregated accounts with custodian banks and may be obtained in the event of a default

of the counterparty. The Fund monitors, on a daily basis, the value of the collateral to ensure it is at least equal to the principal amount of the repurchase agreement (including accrued interest). In the event of a default by the counterparty, realization of the collateral proceeds could be delayed, during which time the value of the collateral may decline.

Delayed Delivery Transactions and When-Issued Securities. The Fund may purchase or sell securities on a delayed delivery or when-issued basis. Payment and delivery may take place after the customary settlement period for that security. The price of the underlying securities and the date when the securities will be delivered and paid for are fixed at the time the transaction is negotiated. During the time a delayed delivery sell is outstanding, the contract is marked-to-market daily and equivalent deliverable securities are held for the transaction. The value of the securities purchased on a delayed delivery or when-issued basis are identified as such in the Fund's Schedule of Investments. The Fund may receive compensation for interest forgone in the purchase of a delayed delivery or when-issued security. With respect to purchase commitments, the Fund identifies securities as segregated in its records with a value at least equal to the amount of the commitment. Losses may arise due to changes in the value of the underlying securities or if the counterparty does not perform under the contract's terms, or if the issuer does not issue the securities due to political, economic, or other factors.

Futures Contracts. The Fund may use futures contracts to manage its exposure to the bond market and to fluctuations in interest rates. Buying futures tends to increase a fund's exposure to the underlying instrument, while selling futures tends to decrease a fund's exposure to the underlying instrument or hedge other fund investments. Upon entering into a futures contract, a fund is required to deposit with a clearing broker, no later than the following business day, an amount ("initial margin") equal to a certain percentage of the face value of the contract. The initial margin may be in the form of cash or securities and is transferred to a segregated account on settlement date. Subsequent payments ("variation margin") are made or received by a fund depending on the daily fluctuations in the value of the futures contract and are accounted for as unrealized gains or losses. Realized gains (losses) are recorded upon the expiration or closing of the futures contract. Securities deposited to meet margin requirements are identified in the Schedule of Investments. Futures contracts involve, to varying degrees, risk of loss in excess of any futures variation margin reflected in the Statement of Assets and Liabilities. The underlying face amount at value of any open futures contracts at period end is shown in the Schedule of Investments under the caption "Futures Contracts." This

amount reflects each contract's exposure to the underlying instrument at period end. Losses may arise from changes in the value of the underlying instruments or if the counterparties do not perform under the contract's terms. Futures contracts are valued at the settlement price established each day by the board of trade or exchange on which they are traded.

Restricted Securities. The Fund may invest in securities that are subject to legal or contractual restrictions on resale. These securities generally may be resold in transactions exempt from registration or to the public if the securities are registered. Disposal of these securities may involve time-consuming negotiations and expense, and prompt sale at an acceptable price may be difficult. Information regarding restricted securities is included at the end of the Fund's Schedule of Investments.

Swap Agreements. The Fund may invest in swaps for the purpose of managing its exposure to interest rate, credit or market risk.

Total return swaps are agreements to exchange the return generated by one instrument or index for the return generated by another instrument, for example, the agreement to pay interest in exchange for a market-linked return based on a notional amount. To the extent the total return of the index exceeds the offsetting interest obligation, a fund will receive a payment from the counterparty. To the extent it is less, a fund will make a payment to the counterparty. Periodic payments received or made by the Fund are recorded in the accompanying Statement of Operations as realized gains or losses, respectively.

Credit default swaps involve the exchange of a fixed rate premium for protection against the loss in value of an underlying debt instrument in the event of a defined credit event (such as payment default or bankruptcy). Under the terms of the swap, one party acts as a "guarantor" receiving a periodic payment that is a fixed percentage applied to a notional principal amount. In return the party agrees to purchase the notional amount of the underlying instrument, at par, if a credit event occurs during the term of the swap. The Fund may enter into credit default swaps in which either it or its counterparty act as guarantors. By acting as the guarantor of a swap, a fund assumes the market and credit risk of the underlying instrument including liquidity and loss of value. Periodic payments and premiums received or made by the Fund are recorded in the accompanying Statement of Operations as realized gains or losses, respectively.

Swaps are marked-to-market daily based on dealer-supplied valuations and changes in value are recorded as unrealized appreciation (depreciation). Gains or losses are realized upon early termination of the swap agreement. Collateral, in the form of cash or

securities, may be required to be held in segregated accounts with a fund's custodian in compliance with swap contracts. Risks may exceed amounts recognized on the Statement of Assets and Liabilities. These risks include changes in the returns of the underlying instruments, failure of the counterparties to perform under the contracts' terms and the possible lack of liquidity with respect to the swap agreements. Details of swap agreements open at period end are included in the Fund's Schedule of Investments under the caption "Swap Agreements."

5. Purchases and Sales of Investments.

Purchases and sales of securities (including the Fixed-Income Central Funds), other than short-term securities, U.S. government securities and in-kind transactions, aggregated $169,467,496 and $130,011,741, respectively.

6. Fees and Other Transactions with Affiliates.

Management Fee. FMR and its affiliates provide the Fund with investment management related services for which the Fund pays a monthly management fee. The management fee is the sum of an individual fund fee rate that is based on an annual rate of .20% of the Fund's average net assets and a group fee rate that averaged .12% during the period. The group fee rate is based upon the average net assets of all the mutual funds advised by FMR. The group fee rate decreases as assets under management increase and increases as assets under management decrease. For the period, the total annualized management fee rate was .32% of the Fund's average net assets.

Distribution and Service Plan. In accordance with Rule 12b-1 of the 1940 Act, the Fund has adopted separate Distribution and Service Plans for each class of shares. Certain classes pay Fidelity Distributors Corporation (FDC), an affiliate of FMR, separate Distribution and Service Fees, each of which is based on an annual percentage of each class' average net assets. In addition, FDC may pay financial intermediaries for selling shares of the Fund and providing shareholder support services. For the period, the Distribution and Service Fee rates and the total amounts paid to and retained by FDC were as follows:

The deferred sales charges range from 3% to 1% for Class B, 1% for Class C, .75% to .50% for certain purchases of Class A shares and .25% for certain purchases of Class T shares.

For the period, sales charge amounts retained by FDC were as follows:

Accounting and Security Lending Fees. Fidelity Service Company, Inc. (FSC), an affiliate of FMR, maintains the Fund's accounting records. The accounting fee is based on the level of average net assets for the month. Under a separate contract, FSC administers the security lending program. The security lending fee is based on the number and duration of lending transactions.

Exchange-In-Kind. During the period, the Fund exchanged securities for shares of two newly created Fidelity Fixed-Income Central Funds, all of which are affiliated investment companies managed by FIMM, an affiliate of FMR. The Fund delivered securities to each Fixed-Income Central Fund in exchange for shares of each respective Fixed-Income Central Fund, as presented in the accompanying table. Each exchange is considered a non-taxable exchange for federal income tax purposes, with no gain or loss recognized by the Fund or its shareholders.

7. Committed Line of Credit.

The Fund participates with other funds managed by FMR in a $4.2 billion credit facility (the "line of credit") to be utilized for temporary or emergency purposes to fund shareholder redemptions or for other short-term liquidity purposes. The Fund has agreed to pay commitment fees on its pro rata portion of the line of credit, which amounted to $1,655 and is reflected in Miscellaneous Expense on the Statement of Operations. During the period, there were no borrowings on this line of credit.

8. Security Lending.

The Fund lends portfolio securities from time to time in order to earn additional income. On the settlement date of the loan, the Fund receives collateral (in the form of U.S. Treasury obligations, letters of credit and/or cash) against the loaned securities and maintains collateral in an amount not less than 100% of the market value of the loaned securities during the period of the loan. The market value of the loaned securities is determined at the close of business of the Fund and any additional required collateral is

delivered to the Fund on the next business day. If the borrower defaults on its obligation to return the securities loaned because of insolvency or other reasons, a fund could experience delays and costs in recovering the securities loaned or in gaining access to the collateral. Any cash collateral received is invested in cash equivalents. At period end, there were no security loans outstanding. Security lending income represents the income earned on investing cash collateral, less fees and expenses associated with the loan, plus any premium payments that may be received on the loan of certain types of securities. Security lending income is presented in the Statement of Operations as a component of interest income Net income from lending portfolio securities during the period amounted to $4,682.

9. Expense Reductions.

Through arrangements with the Fund's custodian, credits realized as a result of uninvested cash balances were used to reduce the Fund's expenses. During the period, these credits reduced the Fund's custody expenses by $6,709. During the period, credits reduced each class' transfer agent expense as noted in the table below.

10. Other.

The Fund's organizational documents provide former and current trustees and officers with a limited indemnification against liabilities arising in connection with the performance of their duties to the Fund. In the normal course of business, the Fund may also enter into contracts that provide general indemnifications. The Fund's maximum exposure under these arrangements is unknown as this would be dependent on future claims that may be made against the Fund. The risk of material loss from such claims is considered remote.

During the period, the Fund's transfer agent, Fidelity Investments Institutional Operations Company, Inc. (FIIOC), an affiliate of Fidelity Management & Research Company, notified the Fund that the fund's books and records did not reflect a conversion of certain Class B to Class A shares upon their conversion date. Management has determined that this did not have a material impact to the Fund's reported net assets or results of operations in the accompanying financial statements. In March 2007, FIIOC converted the relevant Class B shares to Class A shares and recorded the conversion in the books and

records of the Fund. FIIOC has reimbursed the Fund for related audit and legal expenses and is in the process of determining appropriate remediation to affected shareholder accounts.

Report of Independent Registered Public Accounting Firm

To the Trustees of Fidelity Advisor Series II and Shareholders of Fidelity Advisor Short Fixed-Income Fund:

We have audited the accompanying statement of assets and liabilities of Fidelity Advisor Short Fixed-Income Fund (the Fund), a fund of Fidelity Advisor Series II, including the schedule of investments as of February 28, 2007, and the related statement of operations for the six months then ended, the statements of changes in net assets for the six months ended February 28, 2007, for the ten months ended August 31, 2006 and for the year ended October 31, 2005, and the financial highlights for the six months ended February 28, 2007, for the ten months ended August 31, 2006 and for each of the five years in the period ended October 31, 2005. These financial statements and financial highlights are the responsibility of the Fund's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits.

We conducted our audits in accordance with standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. The Fund is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Fund's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of February 28, 2007, by correspondence with the custodians and brokers; where replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of Fidelity Advisor Short Fixed-Income Fund as of February 28, 2007, the results of its operations, the changes in its net assets and the financial highlights for each of the periods indicated above, in conformity with accounting principles generally accepted in the United States of America.

Semiannual Report

Notes to Shareholders:

As discussed in prior shareholder reports, the fund changed its investment approach in the way it invests in the investment-grade debt market, seeking exposure to various types of securities by investing in central funds as well as investing directly in individual investment-grade securities. Central funds are Fidelity mutual funds used by this fund and other Fidelity funds as an investment vehicle to gain pooled exposure to a particular core market sector, such as corporate bonds or mortgage-backed securities. Instead of multiple funds each investing in investment-grade debt securities individually, they can now take advantage of consolidating investments in a single, larger pool of investment-grade debt by investing directly in central funds. Shares of the central funds are offered only to other Fidelity mutual funds and accounts; investors cannot directly invest in them.

It's important to point out that investing in central funds does not impact the fund's investment objective or risk profile, only the mechanics of how we manage its investment portfolio. The portfolio managers continue to be responsible for choosing appropriate investments for their funds, whether they elect to purchase shares of a central fund or individual securities. Fidelity does not charge any additional management fees for central funds.

Investing in central funds does change the way this report presents the fund's holdings. The Investments section continues to list direct investments of the fund, including each central fund. However, many of the individual investment-grade debt securities previously held by the fund were transferred to the central funds, so they are no longer directly held and thus not listed. Information on the underlying holdings of the fixed-income central funds is available at advisor.fidelity.com, and the financial statements are available upon request.

Chairman's Message

(photo_of_Edward_C_Johnson_3d)

Dear Shareholder:

Substantial single-day losses are not uncommon in the equity markets, and when they occur - as in late February - investors can be better served in the long term by buying good stocks at lower prices than by moving their money to the sidelines. While financial markets are always unpredictable, there are a number of time-tested principles that can put the historical odds in your favor.

One of the basic tenets is to invest for the long term. Over time, riding out the markets' inevitable ups and downs has proven much more effective than selling into panic or chasing the hottest trend. Even missing only a few of the markets' best days can significantly diminish investor returns. Patience also affords the benefits of compounding - of earning interest on additional income or reinvested dividends and capital gains. There are tax advantages and cost benefits to consider as well. The more you sell, the more taxes you pay, and the more you trade, the higher the costs. While staying the course doesn't eliminate risk, it can considerably lessen the effect of short-term declines.

You can further manage your investing risk through diversification. And today, more than ever, geographic diversification should be taken into account. Studies indicate that asset allocation is the single most important determinant of a portfolio's long-term success. The right mix of stocks, bonds and cash - aligned to your particular risk tolerance and investment objective - is very important. Age-appropriate rebalancing is also an essential aspect of asset allocation. For younger investors, an emphasis on equities - which historically have been the best performing asset class over time - is encouraged. As investors near their specific goal, such as retirement or sending a child to college, consideration may be given to replacing volatile assets (e.g. common stocks) with more-stable fixed investments (bonds or savings plans).

A third investment principle - investing regularly - can help lower the average cost of your purchases. Investing a certain amount of money each month or quarter helps ensure you won't pay for all your shares at market highs. This strategy - known as dollar cost averaging - also reduces unconstructive "emotion" from investing, helping shareholders avoid selling weak performers just prior to an upswing, or chasing a hot performer just before a correction.

We invite you to contact us via the Internet, through our Investor Centers or over the phone. It is our privilege to provide you the information you need to make the investments that are right for you.

Sincerely,

/s/Edward C. Johnson 3d

Shareholder Expense Example

As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including sales charges (loads) on purchase payments or redemption proceeds, and (2) ongoing costs, including management fees, distribution and/or service (12b-1) fees and other Fund expenses. This Example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds.

The Example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period (September 1, 2006 to February 28, 2007).

Actual Expenses

The first line of the accompanying table for each class of the Fund provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000.00 (for example, an $8,600 account value divided by $1,000.00 = 8.6), then multiply the result by the number in the first line for a class of the Fund under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. In addition, the Fund, as a shareholder in the underlying Fidelity Central Funds, will indirectly bear its pro rata share of the fees and expenses incurred by the underlying Fidelity Central Funds. These fees and expenses are not included in the Fund's annualized expense ratio used to calculate the expense estimate in the table below.

Hypothetical Example for Comparison Purposes

The second line of the accompanying table for each class of the Fund provides information about hypothetical account values and hypothetical expenses based on a Class' actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Class' actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. In addition, the Fund, as a shareholder in the underlying Fidelity Central Funds, will indirectly bear its pro rata share of the fees and expenses incurred by the underlying Fidelity Central Funds. These fees and expenses are not included in the Fund's annualized expense ratio used to calculate the expense estimate in the table below.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transaction costs. Therefore, the second line of the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

Duration shows how much a bond fund's price fluctuates with changes in comparable interest rates. If rates rise 1%, for example, a fund with a five-year duration is likely to lose about 5% of its value. Other factors also can influence a bond fund's performance and share price. Accordingly, a bond fund's actual performance may differ from this example.

Notes to Financial Statements

For the period ended February 28, 2007

1. Organization.

Fidelity Advisor Short Fixed-Income Fund (the Fund) is a fund of Fidelity Advisor Series II (the trust) and is authorized to issue an unlimited number of shares. The trust is registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company organized as a Massachusetts business trust. The Fund offers Class A, Class T, Class B, Class C, and Institutional Class shares, each of which has equal rights as to assets and voting privileges. Each class has exclusive voting rights with respect to matters that affect that class. Class B shares will automatically convert to Class A shares after a holding period of four years from the initial date of purchase. Investment income, realized and unrealized capital gains and losses, the common expenses of the Fund, and certain fund-level expense reductions, if any, are allocated on a pro rata basis to each class based on the relative net assets of each class to the total net assets of the Fund. Each class differs with respect to transfer agent and distribution and service plan fees incurred. Certain expense reductions also differ by class. The financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America, which require management to make certain estimates and assumptions at the date of the financial statements.

2. Investments in Fidelity Central Funds.

The Fund may invest in Fidelity Central Funds which are open-end investment companies available only to other investment companies and accounts managed by Fidelity Management & Research Company (FMR) and its affiliates. The Fund's Schedule of Investments lists each of the Fidelity Central Funds as an investment of the Fund but does not include the underlying holdings of each Fidelity Central Fund. As an Investing Fund, the Fund indirectly bears its proportionate share of the expenses of the underlying Fidelity Central Funds. A complete unaudited list of holdings for each Fidelity Central Fund is available upon request or, for the Fixed-Income Central Funds, at advisor.fidelity.com. The reports are located just after the Fund's financial statements and quarterly reports but are not part of the financial statements or quarterly reports. In addition, the financial statements of the Fidelity Central Funds, which are not covered by the Fund's Report of Independent Registered Public Accounting Firm, are available on the EDGAR Database on the SEC's web site, www.sec.gov, or upon request.

Based on their investment objective, each Fidelity Central Fund may invest or participate in various investment vehicles or strategies that are similar to those of the Fund. These strategies are consistent with the investment objectives of the Fund and may involve certain economic risks which may cause a decline in value of each of the Fidelity

3. Significant Accounting Policies.

The following summarizes the significant accounting policies of the Fund:

Security Valuation. Investments are valued and net asset value per share is calculated (NAV calculation) as of the close of business of the New York Stock Exchange, normally 4:00 p.m. Eastern time. Wherever possible, the Fund uses independent pricing services approved by the Board of Trustees to value its investments. Debt securities, including restricted securities, for which quotations are readily available, are valued by independent pricing services or by dealers who make markets in such securities. Pricing services consider yield or price of bonds of comparable quality, coupon, maturity and type as well as dealer supplied prices.

When current market prices or quotations are not readily available or do not accurately reflect fair value, valuations may be determined in accordance with procedures adopted

Semiannual Report

Notes to Financial Statements - continued

3. Significant Accounting Policies - continued

Security Valuation - continued

by the Board of Trustees. The frequency of when fair value pricing is used is unpredictable. The value of securities used for NAV calculation under fair value pricing may differ from published prices for the same securities. Investments in open-end mutual funds, including the Fidelity Central Funds, are valued at their closing net asset value each business day. Short-term securities with remaining maturities of sixty days or less for which quotations are not readily available are valued at amortized cost, which approximates value.

Investment Transactions and Income. For financial reporting purposes, the Fund's investment holdings and NAV include trades executed through the end of the last business day of the period. The NAV for processing shareholder transactions includes trades executed through the end of the prior business day. Gains and losses on securities sold are determined on the basis of identified cost and may include proceeds received from litigation. Dividend income is recorded on the ex-dividend date. Interest income and income and capital gain distributions from the Fidelity Central Funds are accrued as earned, with any distributions receivable as of period end included in Distributions receivable from Fidelity Central Funds on the Statement of Assets and Liabilities. Interest income includes coupon interest and amortization of premium and accretion of discount on debt securities.

Expenses. Most expenses of the trust can be directly attributed to a fund. Expenses which cannot be directly attributed are apportioned among each Fund in the trust. Expense estimates are accrued in the period to which they relate and adjustments are made when actual amounts are known.

Income Tax Information and Distributions to Shareholders. Each year, the Fund intends to qualify as a regulated investment company by distributing all of its taxable income and realized gains under Subchapter M of the Internal Revenue Code. As a result, no provision for income taxes is required in the accompanying financial statements.

Dividends are declared daily and paid monthly from net investment income. Distributions from realized gains, if any, are recorded on the ex-dividend date. Income dividends and capital gain distributions are declared separately for each class. Income and capital gain distributions are determined in accordance with income tax regulations, which may differ from generally accepted accounting principles.

Capital accounts within the financial statements are adjusted for permanent book-tax differences. These adjustments have no impact on net assets or the results of operations. Temporary book-tax differences will reverse in a subsequent period.

Semiannual Report

3. Significant Accounting Policies - continued

Income Tax Information and Distributions to Shareholders - continued

Book-tax differences are primarily due to futures transactions, swap agreements, prior period premium and discount on debt securities, market discount, deferred trustees compensation, financing transactions, capital loss carryforwards, and losses deferred due to wash sales.

The federal tax cost of investments and unrealized appreciation (depreciation) as of period end were as follows:

New Accounting Pronouncements. In July 2006, Financial Accounting Standards Board Interpretation No. 48, Accounting for Uncertainty in Income Taxes - an interpretation of FASB Statement 109 (FIN 48), was issued and is effective on the last business day of the semiannual reporting period for fiscal years beginning after December 15, 2006. FIN 48 sets forth a threshold for financial statement recognition, measurement and disclosure of a tax position taken or expected to be taken on a tax return. Management is currently evaluating the impact, if any, the adoption of FIN 48 will have on the Fund's net assets, results of operations and financial statement disclosures.

In addition, in September 2006, Statement of Financial Accounting Standards No. 157, Fair Value Measurements (SFAS 157), was issued and is effective for fiscal years beginning after November 15, 2007. SFAS 157 defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. Management is currently evaluating the impact the adoption of SFAS 157 will have on the Fund's financial statement disclosures.

4. Operating Policies.

Repurchase Agreements. FMR has received an Exemptive Order from the Securities and Exchange Commission (the SEC) which permits the Fund and other affiliated entities of FMR to transfer uninvested cash balances into joint trading accounts which are then invested in repurchase agreements. The Fund may also invest directly with institutions in repurchase agreements. Repurchase agreements are collateralized by government or non-government securities. Upon settlement date, collateral is held in segregated accounts with custodian banks and may be obtained in the event of a default

Notes to Financial Statements - continued

Repurchase Agreements - continued

of the counterparty. The Fund monitors, on a daily basis, the value of the collateral to ensure it is at least equal to the principal amount of the repurchase agreement (including accrued interest). In the event of a default by the counterparty, realization of the collateral proceeds could be delayed, during which time the value of the collateral may decline.

Delayed Delivery Transactions and When-Issued Securities. The Fund may purchase or sell securities on a delayed delivery or when-issued basis. Payment and delivery may take place after the customary settlement period for that security. The price of the underlying securities and the date when the securities will be delivered and paid for are fixed at the time the transaction is negotiated. During the time a delayed delivery sell is outstanding, the contract is marked-to-market daily and equivalent deliverable securities are held for the transaction. The value of the securities purchased on a delayed delivery or when-issued basis are identified as such in the Fund's Schedule of Investments. The Fund may receive compensation for interest forgone in the purchase of a delayed delivery or when-issued security. With respect to purchase commitments, the Fund identifies securities as segregated in its records with a value at least equal to the amount of the commitment. Losses may arise due to changes in the value of the underlying securities or if the counterparty does not perform under the contract's terms, or if the issuer does not issue the securities due to political, economic, or other factors.

Futures Contracts. The Fund may use futures contracts to manage its exposure to the bond market and to fluctuations in interest rates. Buying futures tends to increase a fund's exposure to the underlying instrument, while selling futures tends to decrease a fund's exposure to the underlying instrument or hedge other fund investments. Upon entering into a futures contract, a fund is required to deposit with a clearing broker, no later than the following business day, an amount ("initial margin") equal to a certain percentage of the face value of the contract. The initial margin may be in the form of cash or securities and is transferred to a segregated account on settlement date. Subsequent payments ("variation margin") are made or received by a fund depending on the daily fluctuations in the value of the futures contract and are accounted for as unrealized gains or losses. Realized gains (losses) are recorded upon the expiration or closing of the futures contract. Securities deposited to meet margin requirements are identified in the Schedule of Investments. Futures contracts involve, to varying degrees, risk of loss in excess of any futures variation margin reflected in the Statement of Assets and Liabilities. The underlying face amount at value of any open futures contracts at period end is shown in the Schedule of Investments under the caption "Futures Contracts." This

Futures Contracts - continued

amount reflects each contract's exposure to the underlying instrument at period end. Losses may arise from changes in the value of the underlying instruments or if the counterparties do not perform under the contract's terms. Futures contracts are valued at the settlement price established each day by the board of trade or exchange on which they are traded.

Restricted Securities. The Fund may invest in securities that are subject to legal or contractual restrictions on resale. These securities generally may be resold in transactions exempt from registration or to the public if the securities are registered. Disposal of these securities may involve time-consuming negotiations and expense, and prompt sale at an acceptable price may be difficult. Information regarding restricted securities is included at the end of the Fund's Schedule of Investments.

Swap Agreements. The Fund may invest in swaps for the purpose of managing its exposure to interest rate, credit or market risk.

Total return swaps are agreements to exchange the return generated by one instrument or index for the return generated by another instrument, for example, the agreement to pay interest in exchange for a market-linked return based on a notional amount. To the extent the total return of the index exceeds the offsetting interest obligation, a fund will receive a payment from the counterparty. To the extent it is less, a fund will make a payment to the counterparty. Periodic payments received or made by the Fund are recorded in the accompanying Statement of Operations as realized gains or losses, respectively.

Credit default swaps involve the exchange of a fixed rate premium for protection against the loss in value of an underlying debt instrument in the event of a defined credit event (such as payment default or bankruptcy). Under the terms of the swap, one party acts as a "guarantor" receiving a periodic payment that is a fixed percentage applied to a notional principal amount. In return the party agrees to purchase the notional amount of the underlying instrument, at par, if a credit event occurs during the term of the swap. The Fund may enter into credit default swaps in which either it or its counterparty act as guarantors. By acting as the guarantor of a swap, a fund assumes the market and credit risk of the underlying instrument including liquidity and loss of value. Periodic payments and premiums received or made by the Fund are recorded in the accompanying Statement of Operations as realized gains or losses, respectively.

Swaps are marked-to-market daily based on dealer-supplied valuations and changes in value are recorded as unrealized appreciation (depreciation). Gains or losses are realized upon early termination of the swap agreement. Collateral, in the form of cash or

securities, may be required to be held in segregated accounts with a fund's custodian in compliance with swap contracts. Risks may exceed amounts recognized on the Statement of Assets and Liabilities. These risks include changes in the returns of the underlying instruments, failure of the counterparties to perform under the contracts' terms and the possible lack of liquidity with respect to the swap agreements. Details of swap agreements open at period end are included in the Fund's Schedule of Investments under the caption "Swap Agreements."

5. Purchases and Sales of Investments.

Purchases and sales of securities (including the Fixed-Income Central Funds), other than short-term securities, U.S. government securities and in-kind transactions, aggregated $169,467,496 and $130,011,741, respectively.

6. Fees and Other Transactions with Affiliates.

Management Fee. FMR and its affiliates provide the Fund with investment management related services for which the Fund pays a monthly management fee. The management fee is the sum of an individual fund fee rate that is based on an annual rate of .20% of the Fund's average net assets and a group fee rate that averaged .12% during the period. The group fee rate is based upon the average net assets of all the mutual funds advised by FMR. The group fee rate decreases as assets under management increase and increases as assets under management decrease. For the period, the total annualized management fee rate was .32% of the Fund's average net assets.

Distribution and Service Plan. In accordance with Rule 12b-1 of the 1940 Act, the Fund has adopted separate Distribution and Service Plans for each class of shares. Certain classes pay Fidelity Distributors Corporation (FDC), an affiliate of FMR, separate Distribution and Service Fees, each of which is based on an annual percentage of each class' average net assets. In addition, FDC may pay financial intermediaries for selling shares of the Fund and providing shareholder support services. For the period, the Distribution and Service Fee rates and the total amounts paid to and retained by FDC were as follows:

Sales Load. FDC receives a front-end sales charge of up to 1.50% for selling Class A and Class T shares, some of which is paid to financial intermediaries for selling shares of the Fund. FDC receives the proceeds of a contingent deferred sales charges levied on Class A, Class T, Class B and Class C redemptions. These charges depend on the holding period. The deferred sales charges range from 3% to 1% for Class B, 1% for Class C, .75% to .50% for certain purchases of Class A shares and .25% for certain purchases of Class T shares.

For the period, sales charge amounts retained by FDC were as follows:

(FIIOC), an affiliate of FMR, is the transfer, dividend disbursing and shareholder servicing agent for each class of the Fund. FIIOC receives account fees and asset-based fees that vary according to the account size and type of account of the shareholders of the respective classes of the Fund. FIIOC pays for typesetting, printing and mailing of shareholder reports, except proxy statements. For the period, the total transfer agent fees paid by each class to FIIOC, were as follows:

Accounting and Security Lending Fees. Fidelity Service Company, Inc. (FSC), an affiliate of FMR, maintains the Fund's accounting records. The accounting fee is based on the level of average net assets for the month. Under a separate contract, FSC administers the security lending program. The security lending fee is based on the number and duration of lending transactions.

Exchange-In-Kind. During the period, the Fund exchanged securities for shares of two newly created Fidelity Fixed-Income Central Funds, all of which are affiliated investment companies managed by FIMM, an affiliate of FMR. The Fund delivered securities to each Fixed-Income Central Fund in exchange for shares of each respective Fixed-Income Central Fund, as presented in the accompanying table. Each exchange is considered a non-taxable exchange for federal income tax purposes, with no gain or loss recognized by the Fund or its shareholders.

7. Committed Line of Credit.

The Fund participates with other funds managed by FMR in a $4.2 billion credit facility (the "line of credit") to be utilized for temporary or emergency purposes to fund shareholder redemptions or for other short-term liquidity purposes. The Fund has agreed to pay commitment fees on its pro rata portion of the line of credit, which amounted to $1,655 and is reflected in Miscellaneous Expense on the Statement of Operations. During the period, there were no borrowings on this line of credit.

8. Security Lending.

The Fund lends portfolio securities from time to time in order to earn additional income. On the settlement date of the loan, the Fund receives collateral (in the form of U.S. Treasury obligations, letters of credit and/or cash) against the loaned securities and maintains collateral in an amount not less than 100% of the market value of the loaned securities during the period of the loan. The market value of the loaned securities is determined at the close of business of the Fund and any additional required collateral is

delivered to the Fund on the next business day. If the borrower defaults on its obligation to return the securities loaned because of insolvency or other reasons, a fund could experience delays and costs in recovering the securities loaned or in gaining access to the collateral. Any cash collateral received is invested in cash equivalents. At period end, there were no security loans outstanding. Security lending income represents the income earned on investing cash collateral, less fees and expenses associated with the loan, plus any premium payments that may be received on the loan of certain types of securities. Security lending income is presented in the Statement of Operations as a component of interest income Net income from lending portfolio securities during the period amounted to $4,682.

9. Expense Reductions.

Through arrangements with the Fund's custodian, credits realized as a result of uninvested cash balances were used to reduce the Fund's expenses. During the period, these credits reduced the Fund's custody expenses by $6,709. During the period, credits reduced each class' transfer agent expense as noted in the table below.

10. Other.

The Fund's organizational documents provide former and current trustees and officers with a limited indemnification against liabilities arising in connection with the performance of their duties to the Fund. In the normal course of business, the Fund may also enter into contracts that provide general indemnifications. The Fund's maximum exposure under these arrangements is unknown as this would be dependent on future claims that may be made against the Fund. The risk of material loss from such claims is considered remote.

During the period, the Fund's transfer agent, Fidelity Investments Institutional Operations Company, Inc. (FIIOC), an affiliate of Fidelity Management & Research Company, notified the Fund that the fund's books and records did not reflect a conversion of certain Class B to Class A shares upon their conversion date. Management has determined that this did not have a material impact to the Fund's reported net assets or results of operations in the accompanying financial statements. In March 2007, FIIOC converted the relevant Class B shares to Class A shares and recorded the conversion in the books and

Semiannual Report

Report of Independent Registered Public Accounting Firm

To the Trustees of Fidelity Advisor Series II and Shareholders of Fidelity Advisor Short Fixed-Income Fund:

We have audited the accompanying statement of assets and liabilities of Fidelity Advisor Short Fixed-Income Fund (the Fund), a fund of Fidelity Advisor Series II, including the schedule of investments as of February 28, 2007, and the related statement of operations for the six months then ended, the statements of changes in net assets for the six months ended February 28, 2007, for the ten months ended August 31, 2006 and for the year ended October 31, 2005, and the financial highlights for the six months ended February 28, 2007, for the ten months ended August 31, 2006 and for each of the five years in the period ended October 31, 2005. These financial statements and financial highlights are the responsibility of the Fund's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits.

We conducted our audits in accordance with standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. The Fund is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Fund's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of February 28, 2007, by correspondence with the custodians and brokers; where replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of Fidelity Advisor Short Fixed-Income Fund as of February 28, 2007, the results of its operations, the changes in its net assets and the financial highlights for each of the periods indicated above, in conformity with accounting principles generally accepted in the United States of America.
