Shareholder Expense Example

As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, 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 actual expense Example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period (October 7, 2009 to January 31, 2010). The hypothetical expense Example is based on an investment of $1,000 invested for the one-half year period (August 1, 2009 to January 31, 2010).

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. 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 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. 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.

Notes to Consolidated Financial Statements

For the period ended January 31, 2010

1. Organization.

Fidelity Commodity Strategy Central Fund (the Fund) is a non-diversified fund of Fidelity Garrison 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 Massachusetts business trust. Shares of the Fund are only offered to other investment companies and accounts managed by Fidelity Management & Research Company (FMR), or its affiliates (the Investing Funds).

2. Investment in Subsidiary

The Fund may invest in commodity-linked derivative instruments through its investment in the Fidelity Commodity Return Central Cayman Ltd., a wholly owned subsidiary (the "Subsidiary"). The Subsidiary has the ability to invest in commodity-linked derivative instruments, consistent with the investment objective of the Fund. As of January 31, 2010, the Fund held $17,925,459 in the Subsidiary, representing 9.9% of the Fund's net assets.

3. 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 FMR and its affiliates. The Fund's Consolidated Schedule of Investments lists each of the Fidelity Central Funds held as of period end, if any, 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.

The Money Market Central Funds seek preservation of capital and current income and are managed by Fidelity Investments Money Management, Inc. (FIMM), an affiliate of FMR.

A complete unaudited list of holdings for each Fidelity Central Fund is available upon request or at the Securities and Exchange Commission (the SEC) web site at www.sec.gov. 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 SEC web site or upon request.

4. Significant Accounting Policies.

The financial statements have been consolidated and include accounts of the Fund and the Subsidiary. Accordingly, all inter-company transactions and balances have been eliminated.

The consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America, which require

Semiannual Report

4. Significant Accounting Policies - continued

management to make certain estimates and assumptions at the date of the financial statements. Actual results could differ from those estimates. The following summarizes the significant accounting policies of the Fund:

Security Valuation. Investments are valued as of 4:00 p.m. Eastern time on the last calendar day of the period. The Fund uses independent pricing services approved by the Board of Trustees to value its investments. When current market prices or quotations are not readily available or reliable, valuations may be determined in good faith in accordance with procedures adopted by the Board of Trustees. Factors used in determining value may include significant market or security specific events, changes in interest rates and credit quality. The frequency with which these procedures are used cannot be predicted and may be utilized to a significant extent. The value used for net asset value (NAV) calculation under these procedures may differ from published prices for the same securities.

The Fund categorizes the inputs to valuation techniques used to value its investments into a disclosure hierarchy consisting of three levels as shown below.

Level 1 - quoted prices in active markets for identical investments

Level 2 - other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, etc.)

Level 3 - unobservable inputs (including the fund's own assumptions based on the best information available)

Changes in valuation techniques may result in transfers in or out of an assigned level within the disclosure hierarchy. The aggregate value of investments by input level, as of January 31, 2010, for the Fund's investments is included at the end of the Fund's Consolidated Schedule of Investments. Valuation techniques used to value the Fund's investments by major category are as follows.

Debt securities, including restricted securities, are valued based on evaluated quotations received from independent pricing services or from dealers who make markets in such securities. For U.S. government and government agency obligations, pricing services utilize matrix pricing which considers yield or price of bonds of comparable quality, coupon, maturity and type as well as dealer supplied prices and are generally categorized as Level 2 in the hierarchy. For commodity-linked notes, pricing services generally consider the movement of an underlying commodity index as well as other terms of the contract including the leverage factor and any fee and/or interest components of the note and are categorized as Level 2 in the hierarchy. 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 and are categorized as Level 2 in the hierarchy.

Security Valuation - continued

Swaps are marked-to-market daily based on valuations from independent pricing services or dealer-supplied valuations and changes in value are recorded as unrealized appreciation (depreciation). Pricing services utilize matrix pricing which considers comparisons to movements in the underlying index, interest rate curves, credit spread curves, default possibilities and recovery rates and swaps are generally categorized as Level 2 in the hierarchy.

When independent prices are unavailable or unreliable, debt securities and swaps may be valued utilizing pricing matrices which consider similar factors that would be used by independent pricing services. These are generally categorized as Level 2 in the hierarchy but may be Level 3 depending on the circumstances.

Exchange-traded notes (ETNs) are valued at their last sale price or official closing price as reported by an independent pricing service on the primary market or exchange on which they are traded and are categorized as Level 1 in the hierarchy. In the event there were no sales during the day but the exchange reports a closing bid level, ETNs are valued at the closing bid and would be categorized as Level 1 in the hierarchy. In the event there was no closing bid, ETNs may be valued by another method that the Board of Trustees believes reflects fair value in accordance with the Board's fair value pricing policies and may be categorized as Level 2 in the hierarchy.

Futures contracts are valued at the settlement price or official closing price established each day by the board of trade or exchange on which they are traded and are categorized as Level 1 in the hierarchy. Investments in open-end mutual funds, including the Fidelity Money Market Central Funds,are valued at their closing net asset value each business day and are categorized as Level 1 in the hierarchy.

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 per share for processing shareholder transactions is calculated as of the close of business of the New York Stock Exchange (NYSE), normally 4:00 p.m. Eastern time and includes trades executed through the end of the prior business day. Security transactions, including the Fund's investment activity in the Fidelity Central Funds, are accounted for as of trade date. Gains and losses on securities sold are determined on the basis of identified cost. Interest income and distributions from other Fidelity Central Funds are accrued as earned. 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.

4. 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 substantially all of its taxable income and realized gains under Subchapter M of the Internal Revenue Code and filing its U.S. federal tax return. As a result, no provision for income taxes is required. A Fund's federal tax return is subject to examination by the Internal Revenue Service (IRS) for a period of three years.

The Subsidiary is classified as a controlled foreign corporation under Subchapter N of the Internal Revenue Code. Therefore, the Fund is required to increase its taxable income by its share of the Subsidiary's income. Net investment losses of the Subsidiary cannot be deducted by the Fund in the current period nor carried forward to offset taxable income in future periods.

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 consolidated 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.

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

Gross unrealized appreciation	$ 1,452
Gross unrealized depreciation	(701,578)
Net unrealized appreciation (depreciation)	$ (700,126)
Tax cost	$ 190,738,741

5. Operating Policies.

Indexed Securities. The Fund may invest in indexed securities whose values, interest rates and/or redemption prices are linked either directly or inversely to changes in foreign currencies, interest rates, commodities, indices, or other underlying instruments. These securities may be used to increase or decrease its exposure to different underlying instruments and to gain exposure to markets that might be difficult to invest in through conventional securities. Indexed securities may be more volatile than their underlying instruments, but any loss is limited to the amount of the original investment. Gains (losses) realized upon the sale of indexed securities are included in realized gains (losses) on investment securities.

5. Operating Policies - continued

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 Consolidated Schedule of Investments.

6. Investments in Derivative Instruments.

Objectives and Strategies for Investing in Derivative Instruments. The Fund uses derivative instruments ("derivatives"), including futures contracts and swap agreements, in order to meet its investment objectives. The Fund's strategy is to use derivatives as a risk management tool and as an additional way to gain exposure to certain types of assets. The success of any strategy involving derivatives depends on analysis of numerous economic factors, and if the strategies for investment do not work as intended, the Fund may not achieve its objectives.

While utilizing derivatives in pursuit of its investment objectives, the Fund is exposed to certain financial risk relative to those derivatives. This risk is further explained below:

Commodity Risk Commodity risk is the risk that the value of a commodity will fluctuate as a result of changes in market prices.

The following notes provide more detailed information about each derivative type held by the Fund:

Futures Contracts. The Fund uses futures contracts to manage its exposure to the commodities market. A futures contract is an agreement between two parties to buy or sell a specified underlying instrument for a fixed price at a specified future date. 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. Risks of loss may exceed any futures variation margin reflected in the Fund's Consolidated Statement of Assets and Liabilities and may include commodity risk and potential lack of liquidity in the market. Futures have reduced counterparty risk since the exchange's clearinghouse acts as counterparty to all exchange-traded futures. The underlying face amount at value of any open futures contracts at period end is shown in the Consolidated Schedule of Investments under the caption "Futures Contracts." This amount reflects each contract's exposure to the underlying instrument at period end.

Semiannual Report

6. Investments in Derivative Instruments - continued

Futures Contracts - continued

The purchaser or seller of a futures contract is not required to pay for or deliver the instrument unless the contract is held until the delivery date. 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. Securities deposited to meet margin requirements are identified in the Fund's Consolidated Schedule of Investments. Futures contracts are marked-to-market daily and subsequent payments ("variation margin") are made or received by a fund depending on the daily fluctuations in the value of the futures contract. These amounts are reflected as receivables or payables on the Consolidated Statement of Assets and Liabilities and changes in value are recognized as unrealized gain (loss). Realized gain (loss) is recorded upon the expiration or closing of the futures contract. The net realized gain (loss) and change in unrealized gain (loss) on futures contracts during the period is included on the Consolidated Statement of Operations. The total underlying face amount of all open futures contracts at period end is indicative of the volume of this derivative type.

Swap Agreements. The Fund entered into swap agreements, which are contracts between two parties to exchange future cash flows at periodic intervals based on a notional principal amount. Payments are exchanged at specified intervals, accrued daily commencing with the effective date of the contract and recorded as realized gains or losses in the Fund's accompanying Consolidated Statement of Operations. Gains or losses are realized in the event of an early termination of a swap agreement. Any upfront payments made or received upon entering a swap contract to compensate for differences between stated terms of the agreement and prevailing market conditions (e.g. credit spreads, interest rates or other factors) are recorded as realized gains or losses ratably over the term of the swap in the Fund's accompanying Consolidated Statement of Operations. Risks of loss may exceed amounts recognized on the Fund's Consolidated Statement of Assets and Liabilities. In addition, there is the risk of failure by the counterparty to perform under the terms of the agreement and lack of liquidity in the market. Details of swap agreements open at period end are included in the Fund's Consolidated Schedule of Investments under the caption "Swap Agreements." The total notional amount of all open swap agreements at period end is indicative of the volume of this derivative type. Collateral, in the form of cash or securities, may be required to be held in segregated accounts with a fund's custodian bank in accordance with the swap agreement and, if required, is identified in the Fund's Consolidated Schedule of Investments. The Fund could experience delays and costs in gaining access to the collateral even though it is held in the Fund's custodian bank.

6. Investments in Derivative Instruments - continued

Swap Agreements - continued

The Fund entered into total return swap agreements to manage its exposure to the commodities market. Total return swaps are agreements to exchange a market-linked return for the return based on either a fixed or floating interest rate applied to a notional principal amount. To the extent the total return of an index or a reference obligation exceeds the offsetting interest obligation the Fund will receive a payment from the counterparty. To the extent it is less, the Fund will make a payment to the counterparty.

Realized and Change in Unrealized Gain (Loss) on Derivative Instruments. A summary of the Fund's value of derivatives by primary risk exposure as of period end, if any, is included at the end of the Fund's Consolidated Schedule of Investments. The table below reflects the Fund's realized gain (loss) and change in unrealized gain (loss) for derivatives during the period.

Risk Exposure / Derivative Type	Realized Gain (Loss)	Change in Unrealized Gain (Loss)
Commodity Risk
Futures Contracts	$ (55,687)	$ (36,981)
Swap Agreements	2,104,554	(7,460,316)
Total Derivatives Realized and Change in Unrealized Gain (Loss) (a)(b)	$ 2,048,867	$ (7,497,297)

(a) Total derivatives realized gain (loss) included in the Consolidated Statement of Operations is comprised of $(55,687) for futures contracts and $2,104,554 for swap agreements.

(b) Total derivatives change in unrealized gain (loss) included in the Consolidated Statement of Operations is comprised of $(36,981) for futures contracts and $(7,460,316) for swap agreements.

7. Purchases and Sales of Investments.

Purchases and sales of securities, other than short-term securities, aggregated $8,246,197 and $2,548,761, respectively.

8. Fees and Other Transactions with Affiliates.

Management Fee and Expense Contract. FMR Co., Inc. (FMRC), an affiliate of FMR, provides the Fund with investment management services. The Fund does not pay any fees for these services. Pursuant to the Fund's management contract with FMRC, FMR pays FMRC a portion of the management fees it receives from the Investing Funds. In addition, under an expense contract, FMR also pays all other expenses of the Fund, excluding custody fees, the compensation of the independent Trustees, and certain exceptions such as interest expense.

Management Fee and Expense Contract - continued

FMR and its affiliates also provide investment management related services to the Subsidiary. The Subsidiary pays FMR a monthly management fee at the annual rate of .30% of its assets. The Subsidiary also pays certain other expenses including custody and directors' fees.

Sub-Adviser. Geode Capital Management, LLC (Geode), serves as sub-adviser for the Fund. Geode provides discretionary investment advisory services to the Fund and is paid by FMRC for providing these services.

9. Expense Reductions.

FMR has voluntarily agreed to reimburse a portion of the Fund's operating expenses. For the period, the reimbursement reduced the expenses by $102.

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.

At the end of the period, mutual funds managed by FMR or an FMR affiliate were the owners of record of all of the outstanding shares of the Fund.

To the Trustees of Fidelity Garrison Street Trust and the Shareholders of Fidelity Commodity Strategy Central Fund:

In our opinion, the accompanying consolidated statement of assets and liabilities, including the consolidated schedule of investments, and the related consolidated statements of operations and of changes in net assets and the financial highlights present fairly, in all material respects, the financial position of Fidelity Commodity Strategy Central Fund (a fund of Fidelity Garrison Street Trust) at January 31, 2010, the results of its operations for the period indicated, the changes in its net assets for the period indicated and the financial highlights for the period indicated, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as "financial statements") are the responsibility of the Fidelity Commodity Strategy Central Fund's management. Our responsibility is to express an opinion on these financial statements based on our audit. We conducted our audit of these financial statements in accordance with the 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 are free of material misstatement. An audit 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, and evaluating the overall financial statement presentation. We believe that our audit, which included confirmation of securities at January 31, 2010 by correspondence with the custodian and brokers, provides a reasonable basis for our opinion.

Board Approval of Investment Advisory Contracts and Management Fees

Fidelity Commodity Strategy Central Fund

On July 16, 2009, the Board of Trustees, including the Independent Trustees (together, the Board), voted to approve the management contract and sub-advisory agreements (together, the Advisory Contracts) for the fund. The Board, assisted by the advice of fund counsel and Independent Trustees' counsel, considered a broad range of information.

Nature, Extent, and Quality of Services Provided. The Board considered staffing within the investment adviser, FMR Co., Inc., and the sub-adviser (together, the Investment Advisers), including the backgrounds of the fund's investment personnel and the fund's investment objective and discipline.

Resources Dedicated to Investment Management and Support Services. The Board reviewed the size, education, and experience of the Investment Advisers' investment staff, their use of technology, and the Investment Advisers' approach to recruiting, training, and retaining portfolio managers and other research, advisory, and management personnel. The Board noted that Fidelity's analysts have access to a variety of technological tools that enable them to perform both fundamental and quantitative analysis and to specialize in various disciplines. The Board considered Fidelity's extensive global research capabilities that enable the Investment Advisers to aggregate data from various sources in an effort to produce positive investment results. The Board also considered that Fidelity's portfolio managers and analysts have access to daily portfolio attribution that allows for monitoring of a fund's portfolio, as well as an electronic communication system that provides immediate real-time access to research concerning issuers and credit enhancers.

Administrative Services. The Board considered the nature, extent, quality, and cost of advisory and administrative services performed by the Investment Advisers and their affiliates under the Advisory Contracts and under separate agreements covering transfer agency and pricing and bookkeeping services for the fund. The Board also considered the nature and extent of the Investment Advisers' supervision of third party service providers, principally custodians and subcustodians.

Investment Performance. The fund is a new fund and therefore had no historical performance for the Board to review at the time it approved the fund's Advisory Contracts. Once the fund has been in operation for at least one calendar year, the Board will review the fund's absolute and relative investment performance. The Board noted that the fund is designed to offer a liquid investment option for other investment companies and accounts managed by Fidelity Management & Research Company (FMR) or its affiliates and ultimately to enhance the performance of those investment companies and accounts.

Based on its review, the Board concluded that the nature, extent, and quality of the services provided by Fidelity will benefit the fund's shareholders.

Board Approval of Investment Advisory Contracts and
Management Fees - continued

Competitiveness of Management Fee and Total Fund Expenses. The Board considered that FMR pays the fund's management fee on behalf of the fund. The Board also noted that FMR bears all expenses of the fund, except expenses related to the fund's investment activities (primarily custody expenses). Based on its review, the Board concluded that the fund's management fee and projected 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 fund is a new fund and therefore no revenue, cost, or profitability data was available for the Board to review in respect of the fund at the time it approved the Advisory Contracts. In connection with its future renewal of the fund's Advisory Contracts, the Board will consider the level of Fidelity's profits in respect of all the Fidelity funds, as well as the profitability of each fund that invests in this fund.

Economies of Scale. The Board concluded that the realization of economies of scale was not relevant to the approval of Advisory Contracts because the fund pays no advisory fees and FMR bears all other expenses of the fund, except expenses related to the fund's investment activities.

Additional Information Requested by the Board. In order to develop fully the factual basis for consideration of the Advisory Contracts, the Board received additional information on the benefits of pooled investments such as the fund. The Board received information explaining that the fund is a centralized vehicle for the management of securities on a pooled basis. The Board noted that those Fidelity funds investing in the fund will benefit from investing in one centralized fund as portfolio transaction costs are likely to be lower and, for investing funds with smaller allocations, the fund can provide better diversification by taking advantage of the larger asset base in a centralized fund. The Board also received information explaining that the fund's investments will be chosen using an investment discipline developed by Geode Capital Management, the sub-advisor to Fidelity's equity index 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 approved.
