Chairman's Message

(photo_of_Abigail_P_Johnson)

Dear Shareholder:

The turnaround in global capital markets that marked most of 2009 slowed in early 2010, as investors considered the risks to a sustained recovery, including increased political uncertainty, high unemployment, weak consumer spending and potential inflation on the horizon. Financial markets are always unpredictable, of course, but there also are several time-tested investment principles that can help put the 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 can be tax advantages and cost benefits to consider as well. 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 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 "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 by phone. It is our privilege to provide you the information you need to make the investments that are right for you.

Sincerely,

(The chairman's signature appears here.)

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 (September 1, 2009 to February 28, 2010).

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.

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

* Expenses are equal to each Fund's annualized expense ratio, multiplied by the average account value over the period, multiplied by 181/365 (to reflect the one-half year period).

** If certain fees were not voluntarily waived by FMR or its affiliates during the period, the annualized expense ratio for the Arizona Municipal Money Market Fund would have been .51% and the expenses paid in the actual and hypothetical examples above would have been $2.53 and $2.56, respectively.

Weighted Average Maturity as of February 28, 2010
		6 months ago
Years	7.8	8.8

The weighted average maturity is based on the dollar-weighted average length of time until principal payments are expected or until securities reach maturity, taking into account any maturity shortening feature such as a call, refunding or redemption provision.

Duration as of February 28, 2010
		6 months ago
Years	8.3	8.5

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

Notes to Financial Statements

For the period ended February 28, 2010 (Unaudited)

1. Organization.

Fidelity Arizona Municipal Income Fund (the Income Fund) is a fund of Fidelity Union Street Trust. Fidelity Arizona Municipal Money Market Fund (the Money Market Fund) is a fund of Fidelity Union Street Trust II. Each trust is registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company. Fidelity Union Street Trust and Fidelity Union Street Trust II (the trusts) are organized as a Massachusetts business trust and a Delaware statutory trust, respectively. 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 Arizona.

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' Schedules of Investments list each of the Fidelity Central Funds held as of period end, if any, 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.

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 are available on the SEC 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. Actual results could differ from those estimates. The following summarizes the significant accounting policies of the Funds:

Security Valuation. Investments are valued as of 4:00 p.m. Eastern time on the last calendar day of the period. The Income Fund uses independent pricing services approved by the Board of Trustees to value their 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

Security Valuation - continued

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.

Each Fund categorizes the inputs to valuation techniques used to value their 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)

For the Income Fund, 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 February 28, 2010, for each Fund's investments is included at the end of each Fund's Schedule of Investments. Valuation techniques used to value each Fund's investments by major category are as follows.

For the Income Fund, 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 municipal securities, 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. 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.

When independent prices are unavailable or unreliable, debt securities 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.

Investments in open-end mutual funds are valued at their closing net asset value each business day and are categorized as Level 1 in the hierarchy.

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 and are categorized as Level 2 in the hierarchy.

Semiannual Report

3. Significant Accounting Policies - continued

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 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 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.

Expenses. Most expenses of each 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.

The Money Market Fund participated in the U.S. Treasury Department's Temporary Guarantee Program for Money Market Funds (the "Program") through September 18, 2009. The Money Market Fund paid the U.S. Treasury Department fees equal to 0.04% based on the number of shares outstanding as of September 19, 2008 to participate in the Program through September 18, 2009. The expense was borne by the Money Market Fund without regard to any expense limitation in effect for the Money Market Fund.

Income Tax Information and Distributions to Shareholders. Each year, 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. A Fund's federal tax return is subject to examination by the Internal Revenue Service (IRS) for a period of three years.

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.

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

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

Income Tax Information and Distributions to Shareholders - continued

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 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 investment securities and unrealized appreciation (depreciation) as of period end were as follows for each Fund:

	Tax cost	Gross unrealized appreciation	Gross unrealized depreciation	Net unrealized appreciation (depreciation)
Fidelity Arizona Municipal Income Fund	$ 162,738,605	$ 3,955,269	$ (2,349,600)	$ 1,605,669
Fidelity Arizona Municipal Money Market Fund	352,628,805	-	-	-

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.

4. Purchases and Sales of Investments.

Purchases and sales of securities, other than short-term securities, for the Income Fund aggregated $14,833,153 and $4,878,815, respectively.

5. Fees and Other Transactions with Affiliates.

Management Fee. FMR and its affiliates provides the Funds with investment management related services for which the Funds pay a monthly management fee. FMR pays all other expenses, except the compensation of the independent Trustees and certain exceptions such as interest expense, including commitment fees. The management fee paid to FMR by the Funds is reduced by an amount equal to the fees and expenses paid by the Funds to the independent Trustees. Each Fund's management fee is equal to the following annual rate of average net assets:

Fidelity Arizona Municipal Income Fund	.55%
Fidelity Arizona Municipal Money Market Fund	.50%

Semiannual Report

6. Committed Line of Credit.

The Income Fund participates with other funds managed by FMR in a $3.5 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 Arizona Municipal Income Fund

$ 317

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

7. Expense Reductions.

FMR or its affiliates voluntarily agreed to waive certain fees during the period for the Money Market fund. The amount of the waiver is $327,760.

In addition, through arrangements with each applicable Fund's custodian, credits realized as a result of uninvested cash balances were used to reduce each applicable Fund's management fee. During the period, these credits reduced management fee by the following amounts:

Fidelity Arizona Municipal Income Fund	$ 1,437
Fidelity Arizona Municipal Money Market Fund	300

8. 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.

The supply of municipal money market securities has fluctuated significantly due to market volatility. As a result, the Money Market Fund's cash position may be significant during the period.

Board Approval of Investment Advisory Contracts and Management Fees

Fidelity Arizona Municipal Income Fund / Fidelity Arizona Municipal Money Market Fund

Each year, 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 and considers at each of its meetings factors that are relevant to its annual consideration of the renewal of each fund's Advisory Contracts, including the services and support provided to each fund and its shareholders. The Board has established three 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. The Operations Committee meets regularly throughout the year and, among other matters, considers matters specifically related to the annual consideration of the renewal of each fund's Advisory Contracts. The Board, acting directly and through its Committees, requests and receives information concerning the annual consideration of the renewal of each fund's Advisory Contracts. The Board also meets as needed to consider matters specifically related to the Board's annual consideration of the renewal of Advisory Contracts.

At its September 2009 meeting, the Board of Trustees, including the Independent Trustees, unanimously determined to renew each fund's Advisory Contracts. 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 each fund's management fee and total expenses; (iii) the total costs of the services to be provided by and the profits to be realized by Fidelity from its 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.

In considering 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 and through the exercise of its business judgment, 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. The Board's decision to renew the Advisory Contracts was not based on any single factor noted above, but rather was based on a comprehensive consideration of all the information provided to the Board at its meetings throughout the year. The Board, in reaching its determination to renew the Advisory Contracts, 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.

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 backgrounds of the funds' investment personnel 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.

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. In response to the recent financial crisis, Fidelity took a number of actions intended to cut costs and improve efficiency without weakening the investment teams or resources. The Board specifically noted Fidelity's response to the 2008 credit market crisis. The Board noted that Fidelity's analysts have access to a variety of technological tools and market and securities data 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. In addition, the Board considered the trading resources that are an integral 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 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.

The Board noted that the growth of fund assets over time 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 a large variety of mutual fund investor services. The Board noted that Fidelity had taken a number of actions over the previous year that benefited particular funds, including (i) dedicating additional resources to investment research and to restructure and broaden the focus of the investment research teams; (ii) bolstering the senior management team that oversees asset management; (iii) contractually agreeing to reduce the management fee on Fidelity U.S. Bond Index Fund; and (iv) expanding Class A and Class T load waiver categories to increase rollover retention opportunities and create consistent policies across the classes.

Investment Performance. The Board considered whether each fund has operated in accordance with 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 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, 2008, 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 investment performance of the fund was lower than its benchmark for all the periods shown. The Board also reviewed the fund's performance during 2009. The Board discussed with FMR actions that have been taken by FMR to improve the fund's below-benchmark performance.

The Board reviewed the fund's relative investment performance against its peer group and stated that the performance of the fund was in the second quartile for all the periods shown. The Board noted that FMR does not consider that Lipper peer group to be a particularly meaningful comparison for the fund, however, because the peer group combines tax-exempt money market funds from several different states. The Board also reviewed the fund's performance during 2009.

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 and factoring in the unprecedented recent market events, 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. For a more meaningful comparison of management fees, each 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 this regard, the Board realizes that net management fees can vary from year to year because of differences in non-management expenses.

Management Fees - continued

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 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. 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 Arizona Municipal Income Fund's total expenses ranked above its competitive median for 2008.

The Board noted that Arizona Municipal Money Market Fund's total expenses ranked below its competitive median for 2008. The Board considered that Fidelity has been voluntarily waiving part or all of the transfer agent fees and management fees to maintain a minimum yield for Fidelity Arizona Municipal Money Market Fund.

In its review, 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 each fund's total expenses were reasonable, although in the case of Arizona Municipal Income Fund above the median of the universe presented for comparison, 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.

Semiannual Report

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 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 funds' business.

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.

In February 2009, the Board created an Ad Hoc Committee (the "Committee") to analyze economies of scale. The Committee was formed to consider whether FMR attains economies of scale in respect of the management and servicing of the Fidelity funds, whether the Fidelity funds have appropriately benefited from such economies of scale, and whether there is potential for realization of any further economies of scale.

The Board concluded, considering the findings of the Committee, 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 certain topics, including (i) fund performance trends, actions to be taken by FMR to improve certain funds' overall performance and Fidelity's long-term strategies for certain funds; (ii) portfolio manager changes that have occurred during the past year; (iii) Fidelity's fund profitability methodology, the profitability of certain fund service providers, and profitability trends for certain funds; (iv) Fidelity's compensation structure for portfolio managers and key personnel, including its effects on fund profitability, and the extent to which current market conditions have affected retention and recruitment; (v) the selection of and compensation paid by FMR to fund sub-advisers; (vi) Fidelity's fee structures and rationale for recommending different fees among categories of funds; (vii) the rationale for any differences between fund fee structures and fee structures in place for other Fidelity clients; and (viii) explanations for the relative total expenses borne by certain funds and classes, total expense competitive trends, and actions that might be taken by FMR to reduce total expenses for certain funds and classes.

Shareholder Expense Example

As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including redemption fees, and (2) ongoing costs, including management fees and other Fund expenses. This Example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds.

The Example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period (September 1, 2009 to February 28, 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. 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.

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. 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.

Notes to Financial Statements

For the period ended February 28, 2010 (Unaudited)

1. Organization.

Fidelity Maryland Municipal Income Fund (the Fund) is a non-diversified fund of Fidelity Union 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. The Fund may be affected by economic and political developments in the state of Maryland.

2. Significant Accounting Policies.

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 February 28, 2010, for the Fund's investments is included at the end of the Fund's Schedule of Investments. Valuation techniques used to value the Fund's investments by major category are as follows.

Notes to Financial Statements (Unaudited) - continued

2. Significant Accounting Policies - continued

Security Valuation - continued

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 municipal securities, 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. 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.

Investments in open-end mutual 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. Gains and losses on securities sold are determined on the basis of identified cost. Interest income is 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. 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.

Semiannual Report

2. Significant Accounting Policies - continued

Income Tax Information and Distributions to Shareholders - continued

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

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 (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 investment securities and unrealized appreciation (depreciation) as of period end were as follows:

Gross unrealized appreciation	$ 5,871,502
Gross unrealized depreciation	(1,135,722)
Net unrealized appreciation (depreciation)	$ 4,735,780

Tax cost	$ 164,773,518

Short-Term Trading (Redemption) Fees. Shares held in the 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 Fidelity Management & Research Company (FMR), are retained by the Fund and accounted for as an addition to paid in capital.

3. Purchases and Sales of Investments.

Purchases and sales of securities, other than short-term securities, aggregated $13,765,868 and $2,086,462, respectively.

Semiannual Report

Notes to Financial Statements (Unaudited) - continued

4. Fees and Other Transactions with Affiliates.

Management Fee. FMR and its affiliates provide the Fund with investment management related services for which the Fund pays a monthly management fee that is based on an annual rate of .55% of the Fund's average net assets. FMR pays all other expenses, except the compensation of the independent Trustees and certain exceptions 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.

5. Committed Line of Credit.

The Fund participates with other funds managed by FMR in a $3.5 billion credit facility (the "line of credit") to be utilized for temporary or emergency purposes to fund shareholder redemptions or for other short-term liquidity purposes. The Fund has agreed to pay commitment fees on its pro-rata portion of the line of credit, which amounted to $331 and is reflected in Miscellaneous Expense on the Statement of Operations. During the period, there were no borrowings on this line of credit.

6. Expense Reductions.

Through arrangements with the Fund's custodian and transfer agent, credits realized as a result of uninvested cash balances were used to reduce the Fund's management fee. During the period, these credits reduced the Fund's management fee by $1,411.

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.

Board Approval of Investment Advisory Contracts and Management Fees

Fidelity Maryland Municipal Income Fund

Each year, 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 and considers at each of its meetings factors that are relevant to its annual consideration of the renewal of the fund's Advisory Contracts, including the services and support provided to the fund and its shareholders. The Board has established three 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. The Operations Committee meets regularly throughout the year and, among other matters, considers matters specifically related to the annual consideration of the renewal of the fund's Advisory Contracts. The Board, acting directly and through its Committees, requests and receives information concerning the annual consideration of the renewal of the fund's Advisory Contracts. The Board also meets as needed to consider matters specifically related to the Board's annual consideration of the renewal of Advisory Contracts.

At its September 2009 meeting, the Board of Trustees, including the Independent Trustees, unanimously determined to renew the fund's Advisory Contracts. 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 fund's management fee and total expenses; (iii) the total costs of the services to be provided by and the profits to be realized by Fidelity from its relationship with the fund; (iv) the extent to which economies of scale would be realized as the fund grows; and (v) whether fee levels reflect these economies of scale, if any, for the benefit of fund shareholders.

In considering 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 and through the exercise of its business judgment, 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. The Board's decision to renew the Advisory Contracts was not based on any single factor noted above, but rather was based on a comprehensive consideration of all the information provided to the Board at its meetings throughout the year. The Board, in reaching its determination to renew the Advisory Contracts, 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 backgrounds of the fund's investment personnel 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.

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.

Investment Performance. The Board considered whether the fund has operated in accordance with 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 (i) a broad-based securities market index, and (ii) 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, 2008, the fund's cumulative total returns, the cumulative total returns of a broad-based securities market index ("benchmark"), 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.

Semiannual Report

Fidelity Maryland Municipal Income Fund

fid87

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 the one- and five-year periods and the second quartile for the three-year period. The Board also stated that the investment performance of the fund was lower than its benchmark for all the periods shown. The Board discussed with FMR actions that have been taken by FMR to improve the fund's below-benchmark performance. The Board also reviewed the fund's performance during 2009.

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 and factoring in the unprecedented recent market events, 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.

Semiannual Report

Board Approval of Investment Advisory Contracts and
Management Fees - continued

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 12% means that 88% 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 this regard, the Board realizes that net management fees can vary from year to year because of differences in non-management expenses.

Fidelity Maryland Municipal Income Fund

Semiannual Report

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 2008.

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. 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 above its competitive median for 2008.

Based on its review, the Board concluded that the fund's total expenses were reasonable, although above the median of the universe presented for comparison, 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.

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

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

The Board concluded, considering the findings of the Committee, that any potential economies of scale are being shared between fund shareholders and Fidelity in an appropriate manner.

This means that you may have a gain or loss when you sell your shares.
