Chairman's Message

Dear Shareholder:

Many stock and bond markets around the world have been unsettled of late; however, volatility can often lead to opportunity for patient investors. Financial markets are always unpredictable, but 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 redemption fees, and (2) ongoing costs, including management 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 (March 1, 2007 to August 31, 2007).

Actual Expenses

The first line of the accompanying table 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 under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. An annual index fund fee of $10 that is charged once a year may apply for certain accounts with a value of less than $10,000. Various account fees may also be payable to the custodian for certain services. This fee is not included in the table below. If it was, the estimate of expenses you paid during the period would be higher, and your ending account value lower, by this amount. In addition, the Fund, as a shareholder in underlying Fidelity Funds, will indirectly bear its pro rata share of the fees and expenses incurred by the underlying Fidelity 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 provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's 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. An annual index fund fee of $10 that is charged once a year may apply for certain accounts with a value of less than $10,000. Various account fees may also be payable to the custodian for certain services. This fee is not included in the table below. If it was, the estimate of expenses you paid during the period would be higher, and your ending account value lower, by this amount. In addition, the Fund, as a shareholder in underlying Fidelity Funds, will indirectly bear its pro rata share of the fees and expenses incurred by the underlying Fidelity 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.

	Beginning Account Value March 1, 2007	Ending Account Value August 31, 2007	Expenses Paid During Period* March 1, 2007 to August 31, 2007
Actual	$ 1,000.00	$ 1,045.50	$ .41
Hypothetical (5% return per year before expenses)	$ 1,000.00	$ 1,024.73	$ .41

* Expenses are equal to the Fund's annualized expense ratio of .08%; multiplied by the average account value over the period, multiplied by 184/366 (to reflect the one-half year period). The fees and expenses of the underlying Fidelity Funds in which the Fund invests are not included in the Fund's annualized expense ratio.

Notes to Financial Statements

For the period ended August 31, 2007 (Unaudited)

1. Organization.

Fidelity Four-in-One Index Fund (the Fund) is a fund of Fidelity Oxford Street Trust (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 Delaware statutory trust. The Fund invests primarily in a combination of Fidelity index funds (the Underlying Funds) managed by Fidelity Management & Research Company (FMR). Geode Capital Management, LLC serves as sub-adviser for the underlying stock funds.

2. Significant Accounting Policies.

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. The following summarizes the significant accounting policies of the Fund:

Security Valuation. Net asset value per share is calculated as of the close of business of the New York Stock Exchange, normally 4:00 p.m. Eastern time. Investments in the Underlying 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 on the basis of 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. Income and capital gain distributions from the Underlying Funds, if any, are recorded on the ex-dividend date. Interest income is accrued as earned. Interest income includes coupon interest and amortization of premium and accretion of discount on debt securities.

Expenses. Expenses included in the accompanying financial statements reflect the expenses of the Fund and do not include any expenses associated with the Underlying Funds. 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. The Fund adopted the provisions of FASB Interpretation No. 48, Accounting for Uncertainties in Income Taxes (FIN 48), on June 29, 2007. FIN 48 sets forth a minimum threshold for financial statement recognition of the benefit of a tax position taken or expected to be

Notes to Financial Statements (Unaudited) - continued

Income Tax Information and Distributions to Shareholders - continued

taken in a tax return. The implementation of FIN 48 did not result in any unrecognized tax benefits in the accompanying financial statements. Each of the tax years in the three year period ended June 29, 2007 remains subject to examination by the Internal Revenue Service.

Distributions are recorded on the ex-dividend date. 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 short-term gain distributions from the Underlying Funds 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	$ 292,740,471
Unrealized depreciation	(7,384,996)
Net unrealized appreciation (depreciation)	$ 285,355,475
Cost for federal income tax purposes	$ 1,659,183,581

New Accounting Pronouncement. 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.

3. Purchases and Sales of Investments.

Purchases and redemptions of the Underlying Fund shares aggregated $242,512,930 and $61,481,799, respectively.

4. Fees and Other Transactions with Affiliates.

Management Fee. Strategic Advisers, Inc. (Strategic Advisers), an affiliate of FMR, provides the Fund with investment management related services. For these services the Fund pays a monthly management fee to Strategic Advisers. The management fee is computed at an annual rate of .10% of the Fund's average net assets. The management

Semiannual Report

4. Fees and Other Transactions with Affiliates - continued

Management Fee - continued

fee is reduced by an amount equal to the fees and expenses paid by the Fund to the independent Trustees.

Other Transactions. Strategic Advisers has entered into an administration agreement with FMR under which FMR provides management and administrative services (other than investment advisory services) necessary for the operation of the Fund. Pursuant to this agreement, FMR pays all expenses of the Fund, excluding the compensation of the independent Trustees and certain other expenses such as interest expense. FMR also contracts with other Fidelity companies to perform the services necessary for the operation of the Fund. For the services under the agreement, Strategic Advisers pays FMR a monthly administration fee equal to the management fee received by Strategic Advisers, minus an amount equal to an annual rate of .02% of the Fund's average net assets. The Fund does not pay any fees for these services.

5. Expense Reductions.

FMR voluntarily agreed to reimburse the Fund to the extent annual operating expenses exceeded .08% of average net assets. Some expenses, for example interest expense, are excluded from this reimbursement. During the period this reimbursement reduced the Fund's expenses by $187,818.

In addition, 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.

6. 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.

Board Approval of Investment Advisory Contracts and Management Fees

Fidelity Four-in-One Index Fund

Each year, typically in July, the Board of Trustees, including the Independent Trustees (together, the Board), votes on the renewal of the management contract and administration agreement (together, the Advisory Contracts) for the fund. The Board, assisted by the advice of fund counsel and Independent Trustees' counsel, requests and considers a broad range of information throughout the year.

The Board meets regularly each month except August and takes into account throughout the year matters bearing on Advisory Contracts. The Board, acting directly and through its separate committees, considers at each of its meetings factors that are relevant to the annual renewal of the fund's Advisory Contracts, including the services and support provided to the fund and its shareholders. At the time of the renewal, the Board had 12 standing committees, each composed of Independent Trustees with varying backgrounds, to which the Board has assigned specific subject matter responsibilities in order to enhance effective decision-making by the Board. Each committee has adopted a written charter outlining the structure and purposes of the committee. One such committee, the Equity Contract Committee, meets periodically as needed throughout the year to consider matters specifically related to the annual renewal of Advisory Contracts. The committee requests and receives information on, and makes recommendations to the Independent Trustees concerning, the approval and annual review of the Advisory Contracts.

At its July 2007 meeting, the Board of Trustees, including the Independent Trustees, unanimously determined to renew the Advisory Contracts for the fund. In reaching its determination, the Board considered all factors it believed relevant, including (i) the nature, extent, and quality of the services to be provided to the fund and its shareholders (including the investment performance of the fund); (ii) the competitiveness of the management fee and total expenses of the fund; (iii) the total costs of the services to be provided by and the profits to be realized by the investment adviser and its affiliates from the relationship with the fund; (iv) the extent to which economies of scale would be realized as the fund grows; and (v) whether fee levels reflect these economies of scale, if any, for the benefit of fund shareholders.

In determining whether to renew the Advisory Contracts for the fund, the Board ultimately reached a determination, with the assistance of fund counsel and Independent Trustees' counsel, that the renewal of the Advisory Contracts and the compensation to be received by Fidelity under the management contract is consistent with Fidelity's fiduciary duty under applicable law. In addition to evaluating the specific factors noted above, the Board, in reaching its determination, is aware that shareholders in the fund have a broad range of investment choices available to them, including a wide choice among mutual funds offered by competitors to Fidelity, and that the fund's shareholders, with the opportunity to review and weigh the disclosure provided by the fund in its prospectus and other public disclosures, have chosen to invest in this fund, managed by Fidelity.

Management Fees - continued

Nature, Extent, and Quality of Services Provided. The Board considered staffing within the investment adviser, Strategic Advisers, Inc. (Strategic Advisers), and the administrator, FMR, including the backgrounds of the fund's portfolio managers and the fund's investment objective and discipline. The Independent Trustees also had discussions with senior management of Fidelity's investment operations and investment groups. The Board considered the structure of the portfolio manager compensation program and whether this structure provides appropriate incentives.

Resources Dedicated to Investment Management and Support Services. The Board reviewed the size, education, and experience of Strategic Advisers' investment staff, their use of technology, and Strategic Advisers' and FMR's approach to recruiting, training, and retaining portfolio managers and other research, advisory, and management personnel.

Shareholder and Administrative Services. The Board considered (i) the nature, extent, quality, and cost of advisory, administrative, distribution, and shareholder services performed by FMR and its affiliates under the Advisory Contracts and under separate agreements covering transfer agency, pricing and bookkeeping, and securities lending services for the fund; (ii) the nature and extent of FMR's supervision of third party service providers, principally custodians and subcustodians; and (iii) the resources devoted to, and the record of compliance with, the fund's compliance policies and procedures.

The Board noted that the growth of fund assets across the complex allows Fidelity to reinvest in the development of services designed to enhance the value or convenience of the Fidelity funds as investment vehicles. These services include 24-hour access to account information and market information through phone representatives and over the Internet, and investor education materials and asset allocation tools.

Investment in a Large Fund Family. The Board considered the benefits to shareholders of investing in a Fidelity fund, including the benefits of investing in a fund that is part of a large family of funds offering a variety of investment disciplines and providing for a large variety of mutual fund investor services. For example, fund shareholders are offered the privilege of exchanging shares of the fund for shares of other Fidelity funds, as set forth in the fund's prospectus, without paying a sales charge. The Board noted that, since the last Advisory Contract renewals in July 2006, Fidelity has taken a number of actions that benefited particular funds, including (i) dedicating additional resources to investment research and to restructure the investment research teams; (ii) contractually agreeing to reduce the management fee on Fidelity Advisor Floating Rate High Income Fund; (iii) contractually agreeing to reduce the management fees on Fidelity's California, Massachusetts, New Jersey, and New York AMT Tax-Free Money Market Funds, launching new Institutional Classes and Service Classes of these funds, and contractually agreeing to impose expense limitations on these funds; (iv) eliminating the exchange fee on the Fidelity Select Portfolios and reducing the pricing and bookkeeping fee rates for these funds; (v) reducing the maximum transfer agency fee rates on high income funds and certain equity funds; (vi) proposing amended management contracts that, if approved by shareholders, will add a performance adjustment component to the management fees paid by 18 Fidelity Advisor equity funds; (vii) contractually agreeing to reduce fees for Ultra-Short Central Fund and the money market Central Funds; (viii) waiving the Fidelity Advisor funds' contingent deferred sales charge on certain redemptions made through systematic withdrawal programs; and (ix) amending the management contracts for equity and fixed-income funds whose management contracts incorporate a "group fee" structure by adding four new fee "breakpoints" to the group fee rate schedules.

Investment Performance. The Board considered whether the fund has operated within its investment objective, as well as its record of compliance with its investment restrictions. It also reviewed the fund's absolute investment performance, as well as the fund's relative investment performance measured against a proprietary custom index over multiple periods. The Board noted that FMR does not believe that a meaningful peer group exists against which to compare the fund's performance. The following charts considered by the Board show, over the one-, three-, and five-year periods ended December 31, 2006, the fund's cumulative total returns and the cumulative total returns of a proprietary custom index ("benchmark"). The fund's proprietary custom index is an index developed by FMR that represents the performance of the indexes to which the underlying funds seek to correspond and is based on the target weightings of each underlying fund in the fund.

Fidelity Four-in-One Index Fund

The Board stated that the relative investment performance of the fund was lower than its benchmark for all the periods shown, but considered that, unlike the benchmark, the fund has fees and transaction costs.

Based on its review, and giving particular weight to the nature and quality of the resources dedicated by Strategic Advisers and FMR to maintain and improve relative performance, the Board concluded that the nature, extent, and quality of the services provided to the fund will benefit the fund's shareholders, particularly in light of the Board's view that the fund's shareholders benefit from investing in a fund that is part of a large family of funds offering a variety of investment disciplines and services.

Competitiveness of Management Fee and Total Fund Expenses. The Board considered the fund's management fee and total expenses compared to "mapped groups" of competitive funds and classes. Fidelity creates "mapped groups" by combining similar Lipper investment objective categories that have comparable management fee characteristics. Combining Lipper investment objective categories aids the Board's management fee and total expense comparisons by broadening the competitive group used for comparison and by reducing the number of universes to which various Fidelity funds are compared. The Board also considered supplemental information about how the fund's management fee and total expenses ranked relative to groups based on Lipper classifications, which take into account a fund's market capitalization and style.

The Board considered two proprietary management fee comparisons for the 12-month periods shown in the chart below. The group of Lipper funds used by the Board for management fee comparisons is referred to below as the "Total Mapped Group." The Total Mapped Group comparison focuses on a fund's standing relative to the total universe of comparable funds available to investors, in terms of gross management fees before expense reimbursements or caps. "TMG %" represents the percentage of funds in the Total Mapped Group that had management fees that were lower than the fund's. For example, a TMG % of 32% means that 68% of the funds in the Total Mapped Group had higher management fees than the fund. The "Asset-Size Peer Group" (ASPG) comparison focuses on a fund's standing relative to non-Fidelity funds similar in size to the fund within the Total Mapped Group. The ASPG represents at least 15% of the funds in the Total Mapped Group with comparable asset size and management fee characteristics, subject to a minimum of 50 funds (or all funds in the Total Mapped Group if fewer than 50). Additional information, such as the ASPG quartile in which the fund's management fee ranked, is also included in the chart and considered by the Board. For a more meaningful comparison of management fees, the fund is compared on the basis of a hypothetical "net management fee," which is derived by subtracting payments made by FMR (under the administration agreement) for non-management expenses (including pricing and bookkeeping fees and custody fees) from the fund's all-inclusive fee. In this regard, the Board realizes that net management fees can vary from year to year because of differences in non-management expenses, and that non-management expenses may exceed the fund's all-inclusive fee and result in a negative net management fee.

Fidelity Four-in-One Index Fund

The Board noted that the fund's hypothetical net management fee ranked below the median of its Total Mapped Group and below the median of its ASPG for 2006.

Board Approval of Investment Advisory Contracts and
Management Fees - continued

Based on its review, the Board concluded that the fund's management fee was fair and reasonable in light of the services that the fund receives and the other factors considered.

In its review of the fund's total expenses, the Board considered the fund's hypothetical net management fee as well as the fund's all-inclusive fee. The Board also considered other expenses, such as pricing and bookkeeping fees and custodial, legal, and audit fees paid by FMR under the administration agreement. The Board also noted the effects of any waivers and reimbursements on fees and expenses. As part of its review, the Board also considered current and historical total expenses of the fund compared to competitive fund median expenses. The fund is compared to those funds and classes in the Total Mapped Group (used by the Board for management fee comparisons) that have a similar sales load structure.

The Board noted that the fund's total expenses ranked below its competitive median for 2006.

In its review of total expenses, the Board also considered Fidelity fee structures and other information on clients that FMR and its affiliates service in other competitive markets, such as other mutual funds advised or subadvised by FMR or its affiliates, pension plan clients, and other institutional clients.

Based on its review, the Board concluded that the fund's total expenses were reasonable in light of the services that the fund and its shareholders receive and the other factors considered.

Costs of the Services and Profitability. The Board considered the revenues earned and the expenses incurred by Fidelity in conducting the business of developing, marketing, distributing, managing, administering and servicing the fund and its shareholders. The Board also considered the level of Fidelity's profits in respect of all the Fidelity funds.

On an annual basis, FMR presents to the Board Fidelity's profitability for the fund. Fidelity calculates the profitability for each fund, as well as aggregate profitability for groups of Fidelity funds and all Fidelity funds, using a series of detailed revenue and cost allocation methodologies which originate with the audited books and records of Fidelity. The Audit Committee of the Board reviews any significant changes from the prior year's methodologies.

PricewaterhouseCoopers LLP (PwC), independent registered public accounting firm and auditor to Fidelity and certain Fidelity funds, has been engaged annually by the Board as part of the Board's assessment of the results of Fidelity's profitability analysis. PwC's engagement includes the review and assessment of Fidelity's methodologies used in determining the revenues and expenses attributable to Fidelity's mutual fund business, and completion of agreed-upon procedures surrounding the mathematical accuracy of fund profitability and its conformity to allocation methodologies. After considering PwC's reports issued under the engagement and information provided by Fidelity, the Board believes that while other allocation methods may also be reasonable, Fidelity's profitability methodologies are reasonable in all material respects.

Semiannual Report

The Board has also reviewed Fidelity's non-fund businesses and any fall-out benefits related to the mutual fund business as well as cases where Fidelity's affiliates may benefit from or be related to the fund's business.

The Board considered the costs of the services provided by and the profits realized by Fidelity in connection with the operation of the fund and determined that the amount of profit is a fair entrepreneurial profit for the management of the fund.

Economies of Scale. The Board considered whether there have been economies of scale in respect of the management of the Fidelity funds, whether the Fidelity funds (including the fund) have appropriately benefited from any such economies of scale, and whether there is potential for realization of any further economies of scale. The Board considered the extent to which the fund will benefit from economies of scale through increased services to the fund, through waivers or reimbursements, or through fee or expense reductions. The Board concluded that any potential economies of scale are being shared between fund shareholders and Fidelity in an appropriate manner.

Additional Information Requested by the Board. In order to develop fully the factual basis for consideration of the Fidelity funds' Advisory Contracts, the Board requested and received additional information on several topics, including (i) fund performance trends and actions to be taken by FMR to improve certain funds' overall performance; (ii) Fidelity's portfolio manager compensation structure, including its effects on fund profitability and the extent to which portfolio manager compensation is linked to fund performance; (iii) Fidelity's fee structures; (iv) the funds' sub-advisory arrangements; and (v) accounts managed by Fidelity other than the Fidelity funds.

Based on its evaluation of all of the conclusions noted above, and after considering all material factors, the Board ultimately concluded that the advisory fee structures are fair and reasonable, and that the fund's Advisory Contracts should be renewed.
