Chairman's Message

(photo_of_Edward_C_Johnson_3d)

Dear Shareholder:

Stocks are currently on pace to register their fifth straight year of positive returns, although gains could be trimmed if the U.S. economy continues to slow. 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, 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 actual expense Example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period (February 1, 2007 to July 31, 2007) for Massachusetts AMT Tax-Free Money Market and for the entire period (April 18, 2007 to July 31, 2007) for Institutional Class and Service Class. The hypothetical expense Example is based on an investment of $1,000 invested for the one-half year period (February 1, 2007 to July 31, 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. A small balance maintenance fee of $12.00 that is charged once a year may apply for certain accounts with a value of less than $2,000. 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 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. A small balance maintenance fee of $12.00 that is charged once a year may apply for certain accounts with a value of less than $2,000. 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 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.

Semiannual Report

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.

	Beginning Account Value	Ending Account Value July 31, 2007	Expenses Paid During Period
Massachusetts AMT Tax-Free Money Market
Actual	$ 1,000.00	$ 1,016.80	$ 1.70 ^B**

Hypothetical^A	$ 1,000.00	$ 1,022.56	$ 2.26 ^C

^A 5% return per year before expenses

^B Actual expenses are equal to each Class' annualized expense ratio (shown in the table below); multiplied by the average account value over the period, multiplied by 181/365 (to reflect the one-half year period) for Massachusetts AMT Tax-Free Money Market and multiplied by 105/365 (to reflect the period April 18, 2007 to July 31, 2007) for Institutional Class and Service Class.

^C Hypothetical expenses are equal to each Class' annualized expense ratio (shown in the table below); multiplied by the average account value over the period, multiplied by 181/365 (to reflect the one-half year period).

	Annualized Expense Ratio
Massachusetts AMT Tax-Free Money Market	.34%
Institutional Class	.20%
Service Class	.45%

** If changes to management fee and transfer agent contracts, effective April 1, 2007 had been in effect during the entire period, the annualized expense ratio would have been .30% and the expenses paid in the actual and hypothetical examples above would have been $1.50 and $1.51, respectively.

Notes to Financial Statements

For the period ended July 31, 2007 (Unaudited)

1. Organization.

Fidelity Massachusetts AMT Tax-Free Money Market Fund (the Fund) is a fund of Fidelity Massachusetts Municipal 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. The Fund offers Massachusetts AMT Tax-Free Money Market, Institutional Class and Service 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. The fund commenced sale of shares of Institutional Class, Service Class, and the existing class was designated Massachusetts AMT Tax-Free Money Market on April 18, 2007. 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.

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.

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 list of holdings for each Fidelity Central Fund is available upon request or at the SEC's web site at www.sec.gov. In addition, the financial statements of the Fidelity Central Funds are available on the SEC's web site or upon request.

3. 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:

Semiannual Report

Notes to Financial Statements (Unaudited) - continued

3. Significant Accounting Policies - continued

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. As permitted by compliance with certain conditions under Rule 2a-7 of the 1940 Act, securities are valued at amortized cost, which approximates value. Investments in open-end mutual funds, including the Fidelity Central Funds, are valued at their closing net asset value each business day.

Investment Transactions and Income. 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 the 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.

Income Tax Information and Distributions to Shareholders. 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. 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 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.

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. In addition, the Fund claimed a portion of the payment made to redeeming shareholders as a distribution for income tax purposes.

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 deferred trustees compensation, and expiring capital loss carryforwards.

The Fund purchases municipal securities whose interest, in the opinion of the issuer, is free from federal income tax. There is no assurance that the Internal Revenue Service (IRS) will agree with this opinion. In the event the IRS determines that the issuer does not comply with relevant tax requirements, interest payments from a security could become federally taxable, possibly retroactively to the date the security was issued.

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

Unrealized appreciation	$ -
Unrealized depreciation	-
Net unrealized appreciation (depreciation)	$ -
Cost for federal income tax purposes	$ 2,904,396,993

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.

4. Operating Policies.

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.

5. Fees and Other Transactions with Affiliates.

Management Fee and Expense Contract. FMR and its affiliates provide the Fund with investment management related services for which the Fund pays a monthly management fee. The Board of Trustees approved an amendment to the management contract lowering the management fee from .43% to .20% of average net assets effective April 1, 2007. Under the amended management contract, FMR will pay all other fund-level expenses except the compensation of the independent Trustees and certain

Notes to Financial Statements (Unaudited) - continued

Management Fee and Expense Contract - continued

expenses such as interest expense, including commitment fees. The management fee paid to FMR by the Fund is reduced by an amount equal to the fees and expenses paid by the Fund to the independent Trustees. For the period the total annualized management fee rate was .27% of the Fund's average net assets.

In addition, the Board of Trustees approved a new expense contract for Massachusetts AMT Tax-Free Money Market effective April 1, 2007. Under the expense contract, FMR pays class level expenses so that the total expenses do not exceed, expressed as a percentage of class average net assets, .35%, with certain exceptions such as interest expense, including commitment fees.

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. Service Class pays Fidelity Distributors Corporation (FDC), an affiliate of FMR, a Service Fee based on an annual percentage of Service 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 Service Fee rate and the total amount paid to and retained by FDC were as follows:

	Service Fee	Paid to FDC	Retained by FDC
Service Class	.25%	$ 72	$ 72

Transfer Agent and Accounting Fees. Citibank, N.A. (Citibank) is the custodian, transfer agent, and shareholder servicing agent for the Fund. Citibank has entered into a sub-arrangement with Fidelity Service Company, Inc. (FSC), an affiliate of FMR, under which FSC performs the activities associated with the Fund's transfer and shareholder servicing agent and accounting functions. The Board of Trustees approved a new transfer agent contract with Citibank and a new sub-arrangement with FSC effective April 1, 2007. Under the new contract, transfer agent fees for each class are based on an annual rate, expressed as a percentage of each class' average net assets, of .10% for Massachusetts AMT Tax-Free Money Market and .05% each for Institutional Class shares and Service Class shares. Prior to April 1, 2007, FMR paid for the transfer agent fees on behalf of Massachusetts AMT Tax-Free Money Market under the terms of the management fee contract. FSC 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 FSC were as follows:

6. Expense Reductions.

Prior to April 1, 2007, FMR voluntarily agreed to reimburse the Fund to the extent operating expenses exceeded .40% of average net assets. Some expenses, for example interest expense, including commitment fees, were excluded from this reimbursement. During the period, this reimbursement reduced the Fund's expenses by $133,063. Effective April 1, 2007, under the new expense contract for Massachusetts AMT Tax-Free Money Market, the voluntary expense limitation was eliminated. Effective April 18, 2007, FMR has contractually agreed to reimburse Institutional Class and Service Class to the extent that annual operating expenses, expressed as a percentage of each class' average net assets, exceed .20% and .45%, respectively. During the period, this reimbursement reduced Institutional Class and Service Class expenses by $198,034 and $16, respectively.

In addition, 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 expenses by $805,512. During the period, credits reduced each class' transfer agent expense as noted in the table below.

	Transfer Agent expense reduction
Massachusetts AMT Tax-Free Money Market	$ 15,701
Institutional Class	335
	$ 16,036

Semiannual Report

Notes to Financial Statements (Unaudited) - continued

7. 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.

8. Distributions to Shareholders.

Distributions to shareholders of each class were as follows:

	Six months ended July 31, 2007^A	Year ended January 31, 2007

Board Approval of Investment Advisory Contracts and Management Fees

Fidelity Massachusetts AMT Tax-Free Money Market Fund

On March 15, 2007, the Board of Trustees, including the Independent Trustees (together, the Board), voted to approve an amended and restated management contract (the Amended Contract) for the fund, effective April 1, 2007. The Amended Contract lowers the fund's management fee from 43 basis points to 20 basis points of the fund's average daily net assets. The Board, assisted by the advice of fund counsel and Independent Trustees' counsel, considered a broad range of information.

In determining whether to approve the Amended Contract for the fund, the Board was 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.

Nature, Extent, and Quality of Services Provided by Fidelity. The Board considered staffing within the investment adviser, FMR, and the sub-advisers (together, the Investment Advisers), including the background of the fund's portfolio manager and the fund's investment objective and discipline.

Shareholder and Administrative Services. The Board considered the nature, quality, cost and extent of advisory, administrative, distribution and shareholder services performed by the Investment Advisers and affiliated companies.

Investment Performance. The Board noted that the approval of the Amended Contract would not change the fund's portfolio manager, the investment processes, the level or nature of services provided, the resources and personnel allocated, or its trading and compliance operations.

Based on this review of services, the Board concluded that the nature, extent, and quality of services provided to the fund will benefit shareholders of the fund.

Competitiveness of Management Fees and Total Fund Expenses. The Board considered that under the fund's existing management contract, the fund was paying an all-inclusive management fee, whereby FMR was responsible for payment of virtually all fund-level expenses. In approving the Amended Contract, the Board considered that the Amended Contract requires FMR to pay fund-level expenses (such as custody, pricing and bookkeeping, legal, and audit fees), but not class-level expenses (such as transfer agent fees and 12b-1 fees). The Board also considered that the Amended Contract reduces the fund's management fee from 43 basis points to 20 basis points of the fund's average daily assets. The Board noted that the lower management fee rate proposed for the fund would have ranked the fund's management fee below the median of its competitors for 2006.

Semiannual Report

In connection with its review of the fund's total expenses, the Board considered the fund's management fee as well as the fund's non-management expenses, such as transfer agent fees. The Board approved changes (effective April 1, 2007) in the contractual arrangements for the fund that (i) set the transfer agent fee at 10 basis points, and (ii) limit total expenses of the fund to 35 basis points, pursuant to a new expense contract. The Board noted that projected total expenses for the fund's shareholders would be 30 basis points, and that total expenses may not exceed 35 basis points without Board and shareholder approval.

The Board recognized that, although the new flat transfer agent fee rate would be higher than the effective rate for calendar year 2006 (approximately 7.6 bp), total expenses paid by shareholders would be 5 to 10 basis points lower under the new contractual expense arrangements. The Board also noted that the projected total expenses of the fund would have ranked below the median of its competitors for 2006.

Based on this review, the Board concluded that the fund's management fee and 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. In connection with its approval of the fund's Amended Contract, the Board did not consider data regarding the impact on Fidelity's costs of services, revenues, or profitability from the new arrangement because it was approving an arrangement that reduces the management fee and total expenses that the fund pays. The Board noted Fidelity's assertion that reducing the management fee for the fund would reduce Fidelity's profitability. In connection with its future renewal of the fund's management contract and sub-advisory agreements, the Board will consider 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.

Economies of Scale. In connection with its approval of the fund's Amended Contract, the Board did not consider economies of scale because the arrangement lowers the fund's management fee and, under the expense contract, FMR will bear all class-level expenses of the fund's existing class of shareholders so that the class's total expenses do not exceed 35 basis points. In connection with its future renewal of the fund's management contract and sub-advisory agreements, the Board will consider 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.

Based on its evaluation of all of the conclusions noted above, and after consideration of all material factors, the Board concluded that the advisory fee structure is fair and reasonable, and that the Amended Contract should be approved.

Semiannual Report

Board Approval of Investment Advisory Contracts and
Management Fees - continued

Each year, typically in June, the Board of Trustees, including the Independent Trustees (together, the Board), votes on the renewal of 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, 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 Fixed-Income 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 June 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. The Board also approved amendments to the fund's agreements with foreign sub-advisers to clarify that each sub-adviser provides services as an independent contractor.

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.

Semiannual Report

Nature, Extent, and Quality of Services Provided. The Board considered staffing within the investment adviser, FMR, and the sub-advisers (together, the Investment Advisers), including the background of the fund's portfolio manager 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 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 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 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 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. In addition, the Board considered the trading resources that are an integrated part of the fixed-income portfolio management investment process.

Shareholder and Administrative Services. The Board considered (i) the nature, extent, quality, and cost of advisory, administrative, distribution, and shareholder 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; (ii) the nature and extent of the Investment Advisers' 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 June 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 peer group of mutual funds deemed appropriate by the Board over multiple periods. 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 a range of cumulative total returns of a peer group of mutual funds identified by Lipper Inc. as having an investment objective similar to that of the fund. (The fund did not offer Institutional Class or Service Class as of December 31, 2006.) The box within each chart shows the 25th percentile return (bottom of box) and the 75th percentile return (top of box) of the peer group. Returns shown above the box are in the first quartile and returns shown below the box are in the fourth quartile. The percentage beaten number noted below each chart corresponds to the percentile box and represents the percentage of funds in the peer group whose performance was equal to or lower than that of the fund.

Semiannual Report

Fidelity Massachusetts AMT Tax-Free Money Market Fund

The Board reviewed the fund's relative investment performance against its peer group and stated that the performance of the fund was in the first quartile for all the periods shown.

Based on its review, and giving particular weight to the nature and quality of the resources dedicated by the Investment Advisers 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 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" and, for the reasons explained above, is broader than the Lipper peer group used by the Board for performance comparisons. 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 19% means that 81% 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 for non-management expenses (including transfer agent fees, pricing and bookkeeping fees, and custody fees) from the fund's all-inclusive fee (in effect through March 31, 2007). In this regard, the Board realizes that net management fees can vary from year to year because of differences in non-management expenses. The Board noted, however, that FMR does not pay transfer agent fees or other "class-level" expenses (including 12b-1 fees, if applicable) under the fund's amended and restated management contract, effective April 1, 2007.

Semiannual Report

Management Fees - continued

Fidelity Massachusetts AMT Tax-Free Money Market 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.

Semiannual Report

Furthermore, the Board considered that, on March 15, 2007, after the periods shown in the chart above, it had approved an amended and restated management contract for the fund (effective April 1, 2007) that (i) lowered the fund's management fee from 43 basis points to 20 basis points, and (ii) provides that FMR will pay all "fund-level" expenses out of the management fee, with certain limited exceptions. (Transfer agent fees and 12b-1 fees, if applicable, currently are the only "class-level" expenses.) The Board noted that, if the amended and restated management contract had been in effect for 2006, 91% of the funds in the Total Mapped Group would have had higher management fees than the fund, and the fund's management fee would have ranked in the first ASPG quartile.

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 transfer agent fees, pricing and bookkeeping fees, and custodial, legal, and audit fees, paid by FMR under the all-inclusive arrangement (in effect through March 31, 2007). The Board noted, however, that FMR does not pay transfer agent fees or other "class-level" expenses (including 12b-1 fees, if applicable) under the fund's amended and restated management contract, effective April 1, 2007. 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. The Board considered that, if the fund's lower management fee had been in effect for 2006, it would have reduced the fund's total expenses by 10 basis points.

Furthermore, the Board considered that, on March 15, 2007, it had approved changes (effective April 1, 2007) in the contractual arrangements for the fund that (i) have the effect of setting the total "fund-level" expenses (including, among certain other expenses, the management fee) for each class at 20 basis points, (ii) set the "class-level" transfer agent fee for Fidelity Massachusetts AMT Tax-Free Money Market (retail class) at a fixed rate of 10 basis points, and (iii) limit the total expenses of Fidelity Massachusetts AMT Tax-Free Money Market (retail class) to 35 basis points. These contractual arrangements may not be increased without the approval of the Board and, in the case of (i) and (iii), the shareholders of the applicable class. Institutional Class and Service Class (which commenced operations on April 17, 2007) are subject to different "class-level" expenses (transfer agent fees and 12b-1 fees). In addition, the Board considered that, effective April 18, 2007, FMR contractually agreed to limit the total expenses of Institutional Class and Service Class to 20 basis points and 45 basis points, respectively. These contractual arrangements may not be increased without Board approval.

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.

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.

Semiannual Report

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) Fidelity's fund profitability methodology, profitability by investment discipline, and profitability trends within certain funds; (ii) Fidelity's compensation structure relative to competitors and its effect on profitability; (iii) funds and accounts managed by Fidelity other than the Fidelity funds, including fee arrangements; (iv) the total expenses of certain funds and classes relative to competitors; (v) fund performance trends; (vi) fall-out benefits received by certain Fidelity affiliates; and (vii) Fidelity's fee structures.

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.

Dear Shareholder:

Sincerely,

Edward C. Johnson 3d

Semiannual Report

Shareholder Expense Example

As a shareholder of a 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 Funds 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 (February 1, 2007 to July 31, 2007).

Actual Expenses

The first line of the accompanying table for each 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 fund under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. A small balance maintenance fee of $12.00 that is charged once a year may apply for certain accounts with a value of less than $2,000. 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, each 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 fund provides information about hypothetical account values and hypothetical expenses based on a 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. A small balance maintenance fee of $12.00 that is charged once a year may apply for certain accounts with a value of less than $2,000. 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, each 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.

Years	6.8	6.7

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 July 31, 2007 (Unaudited)

1. Organization.

Fidelity Massachusetts Municipal Income Fund (the Income Fund) and Fidelity Massachusetts Municipal Money Market Fund (the Money Market Fund) are funds of Fidelity Massachusetts Municipal Trust (the trust). 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 Income Fund is a non-diversified fund. Each Fund is authorized to issue an unlimited number of shares. Each Fund may be affected by economic and political developments in the state of Massachusetts.

2. Investments in Fidelity Central Funds.

The Funds 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 Funds' Schedule of Investments lists each of the Fidelity Central Funds as an investment of each Fund, but does not include the underlying holdings of each Fidelity Central Fund. As an Investing Fund, the Funds indirectly bear their 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.

3. Significant Accounting Policies.

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, each Fund uses independent pricing services approved by the Board of Trustees to value their investments. For the Income Fund, 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.

3. Significant Accounting Policies - continued

Security Valuation - continued

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.

As permitted by compliance with certain conditions under Rule 2a-7 of the 1940 Act, securities owned by the Money Market Fund are valued at amortized cost which approximates value.

Investment Transactions and Income. For financial reporting purposes, the Funds' 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 for the Income Fund and trades executed through the end of the current business day for the Money Market Fund. Gains and losses on securities sold are determined on the basis of identified cost. Interest income and distributions from the Fidelity Central Funds are accrued as earned. Interest income includes coupon interest and amortization of premium and accretion of discount on debt securities.

Income Tax Information and Distributions to Shareholders. Each 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. Each 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 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.

3. Significant Accounting Policies - continued

Income Tax Information and Distributions to Shareholders - continued

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 and capital gain distributions are determined in accordance with income tax regulations, which may differ from generally accepted accounting principles. In addition, the Funds claimed a portion of the payment made to redeeming shareholders as a distribution for income tax purposes.

Book-tax differences are primarily due to futures transactions, market discount, deferred trustees compensation, expiring capital loss carryforwards and losses deferred due to futures transactions and excise tax regulations.

The Funds purchase municipal securities whose interest, in the opinion of the issuer, is free from federal income tax. There is no assurance that the Internal Revenue Service (IRS) will agree with this opinion. In the event the IRS determines that the issuer does not comply with relevant tax requirements, interest payments from a security could become federally taxable, possibly retroactively to the date the security was issued.

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

	Cost for Federal Income Tax Purposes	Unrealized Appreciation	Unrealized Depreciation	Net Unrealized Appreciation/ (Depreciation)
Fidelity Massachusetts Municipal Income Fund	$ 1,800,558,482	$ 34,811,999	$ (11,363,582)	$ 23,448,417
Fidelity Massachusetts Municipal Money Market Fund	4,790,119,990	-	-	-

Short-Term Trading (Redemption) Fees. Shares held in the Income Fund less than 30 days are subject to a redemption fee equal to .50% of the proceeds of the redeemed shares. All redemption fees, including any estimated redemption fees paid by FMR, are retained by the Fund and accounted for as an addition to paid in capital.

Notes to Financial Statements (Unaudited) - continued

4. Operating Policies.

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. Certain Funds 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 each applicable Fund's Schedule of Investments.

5. Purchases and Sales of Investments.

Purchases and sales of securities, other than short-term securities, for the Income Fund aggregated $187,902,012 and $202,508,103, respectively.

6. Fees and Other Transactions with Affiliates.

Management Fee. FMR and its affiliates provide the Funds with investment management related services for which the Funds pay a monthly management fee. The management fee is the sum of an individual fund fee rate and a group fee rate. The individual fund fee rate is applied to each Fund's average net assets. 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, each Fund's annualized management fee rate expressed as a percentage of each Fund's average net assets was as follows:

	Individual Rate	Group Rate	Total
Fidelity Massachusetts Municipal Income Fund	.25%	.12%	.37%
Fidelity Massachusetts Municipal Money Market Fund	.25%	.12%	.37%

Semiannual Report

6. Fees and Other Transactions with Affiliates - continued

Transfer Agent and Accounting Fees. Citibank, N.A. (Citibank) is the custodian, transfer agent and shareholder servicing agent for the Funds. Citibank has entered into a sub-arrangement with Fidelity Service Company, Inc. (FSC), an affiliate of FMR, under which FSC performs the activities associated with the Funds' transfer and shareholder servicing agent and accounting functions. The Funds pay account fees and asset-based fees that vary according to account size and type of account. FSC pays for typesetting, printing and mailing of shareholder reports, except proxy statements. The accounting fee is based on the level of average net assets for the month. For the period, the transfer agent fees were equivalent to the following annualized rates expressed as a percentage of average net assets:

Fidelity Massachusetts Municipal Income Fund	.07%
Fidelity Massachusetts Municipal Money Market Fund	.13%

7. Committed Line of Credit.

The Income 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 participating funds have agreed to pay commitment fees on their pro rata portion of the line of credit, which is reflected in Miscellaneous Expense on the Statement of Operations, and is as follows:

Fidelity Massachusetts Municipal Income Fund

1,153

During the period, there were no borrowings on this line of credit.

8. Expense Reductions.

Through arrangements with the Income Fund's and Fidelity Massachusetts Municipal Money Market Fund's custodian and transfer agent, credits realized as a result of uninvested cash balances were used to reduce fund expenses. These expense reductions are noted in the table below.

	Custody expense reduction	Transfer Agent expense reduction

Fidelity Massachusetts Municipal Income Fund	$ 12,998	$ 295,710
Fidelity Massachusetts Municipal Money Market Fund	36,618	2,580,088

Semiannual Report

Notes to Financial Statements (Unaudited) - continued

9. Other.

The Funds' 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 Funds. In the normal course of business, the Funds may also enter into contracts that provide general indemnifications. The Funds' maximum exposure under these arrangements is unknown as this would be dependent on future claims that may be made against the Funds. The risk of material loss from such claims is considered remote.

Board Approval of Investment Advisory Contracts and Management Fees

Fidelity Massachusetts Municipal Income Fund / Fidelity Massachusetts Municipal Money Market Fund

Each year, typically in June, the Board of Trustees, including the Independent Trustees (together, the Board), votes on the renewal of the management contract and sub-advisory agreements (together, the Advisory Contracts) for each 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 each fund's Advisory Contracts, including the services and support provided to each 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 Fixed-Income 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 June 2007 meeting, the Board of Trustees, including the Independent Trustees, unanimously determined to renew the Advisory Contracts for each 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 each fund and its shareholders (including the investment performance of each fund); (ii) the competitiveness of the management fee and total expenses of each 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 each fund; (iv) the extent to which economies of scale would be realized as each fund grows; and (v) whether fee levels reflect these economies of scale, if any, for the benefit of fund shareholders. The Board also approved amendments to each fund's agreements with foreign sub-advisers to clarify that each sub-adviser provides services as an independent contractor.

In determining whether to renew the Advisory Contracts for each 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 contracts 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 each 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 each 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 that fund, managed by Fidelity.

Nature, Extent, and Quality of Services Provided. The Board considered staffing within the investment adviser, FMR, and the sub-advisers (together, the Investment Advisers), including the backgrounds of the funds' portfolio managers and the funds' investment objectives and disciplines. 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.

Shareholder and Administrative Services. The Board considered (i) the nature, extent, quality, and cost of advisory, administrative, distribution, and shareholder 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 each fund; (ii) the nature and extent of the Investment Advisers' supervision of third party service providers, principally custodians and subcustodians; and (iii) the resources devoted to, and the record of compliance with, each fund's compliance policies and procedures.

Semiannual Report

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 a 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 June 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 each fund has operated within its investment objective, as well as its record of compliance with its investment restrictions. It also reviewed each fund's absolute investment performance, as well as each fund's relative investment performance measured against (i) a broad-based securities market index (bond fund only, as money market funds are typically not compared against a market index), and (ii) a peer group of mutual funds deemed appropriate by the Board over multiple periods. For each fund, 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, the cumulative total returns of a broad-based securities market index ("benchmark") (bond fund only), and a range of cumulative total returns of a peer group of mutual funds identified by Lipper Inc. as having an investment objective similar to that of the fund. The box within each chart shows the 25th percentile return (bottom of box) and the 75th percentile return (top of box) of the peer group. Returns shown above the box are in the first quartile and returns shown below the box are in the fourth quartile. The percentage beaten number noted below each chart corresponds to the percentile box and represents the percentage of funds in the peer group whose performance was equal to or lower than that of the fund.

The Board reviewed the fund's relative investment performance against its peer group and stated that the performance of the fund was in the first quartile for all the periods shown. The Board also stated that the relative investment performance of the fund was lower than its benchmark for the one- and five-year periods, although the fund's three-year cumulative total return compared favorably to its benchmark.

Semiannual Report

Fidelity Massachusetts Municipal Money Market Fund

The Board reviewed the fund's relative investment performance against its peer group and stated that the performance of the fund was in the first quartile for all the periods shown.

Based on its review, and giving particular weight to the nature and quality of the resources dedicated by the Investment Advisers to maintain and improve relative performance, the Board concluded that the nature, extent, and quality of the services provided to each fund will benefit each fund's shareholders, particularly in light of the Board's view that each 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 each 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 considered two proprietary management fee comparisons for the 12-month periods shown in the charts below. The group of Lipper funds used by the Board for management fee comparisons is referred to below as the "Total Mapped Group" and, for the reasons explained above, is broader than the Lipper peer group used by the Board for performance comparisons. 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 a fund's. For example, a TMG % of 26% would mean that 74% of the funds in the Total Mapped Group had higher management fees than a 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 a fund's management fee ranked, is also included in the charts and considered by the Board.

Semiannual Report

Fidelity Massachusetts Municipal Money Market Fund

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

Based on its review, the Board concluded that each 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 each fund's total expenses, the Board considered the fund's management fee as well as other fund expenses, such as transfer agent fees, pricing and bookkeeping fees, and custodial, legal, and audit fees. 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 each fund compared to competitive fund median expenses. Each 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 each fund's total expenses ranked below its competitive median for 2006.

Semiannual Report

Board Approval of Investment Advisory Contracts and
Management Fees - continued

Based on its review, the Board concluded that each 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 each 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 each 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.

The Board considered the costs of the services provided by and the profits realized by Fidelity in connection with the operation of each fund and determined that the amount of profit is a fair entrepreneurial profit for the management of each 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 each 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 each fund will benefit from economies of scale through increased services to the fund, through waivers or reimbursements, or through fee or expense reductions, including reductions that occur through operation of the transfer agent agreement. The transfer agent fee varies in part based on the number of accounts in a fund. If the number of accounts decreases or the average account size increases, the overall transfer agent fee rate decreases.

Semiannual Report

The Board recognized that each fund's management contracts incorporate a "group fee" structure, which provides for lower group fee rates as total fund assets under FMR's management increase, and for higher group fee rates as total fund assets under FMR's management decrease. FMR determines the group fee rates based on a tiered asset "breakpoint" schedule. In connection with the renewal of each fund's management contract, the Board approved amendments to each fund's management contract that added four new fee breakpoints to the group fee rate schedule for assets under FMR's management above $1,386 billion. The Board considered that the group fee rate declines under both the present and amended schedules, but that under the amended schedule, the group fee rate declines faster as assets under FMR's management exceed $1,386 billion. The Board considered that the group fee is designed to deliver the benefits of economies of scale to fund shareholders when total fund assets increase, even if assets of any particular fund are unchanged or have declined, because some portion of Fidelity's costs are attributable to services provided to all Fidelity funds, and all funds benefit if those costs can be allocated among more assets. The Board concluded that, given the group fee structure, fund shareholders will achieve a certain level of economies of scale as assets under FMR's management increase at the fund complex level, regardless of whether Fidelity achieves any such economies of scale.

The Board further concluded that any potential economies of scale are being shared between fund shareholders and Fidelity in an appropriate manner.
