Chairman's Message

(photo_of_Edward_C_Johnson_3d)

Dear Shareholder:

During the past year or so, much has been reported about the mutual fund industry, and much of it has been more critical than I believe is warranted. Allegations that some companies have been less than forthright with their shareholders have cast a shadow on the entire industry. I continue to find these reports disturbing, and assert that they do not create an accurate picture of the industry overall. Therefore, I would like to remind everyone where Fidelity stands on these issues. I will say two things specifically regarding allegations that some mutual fund companies were in violation of the Securities and Exchange Commission's forward pricing rules or were involved in so-called "market timing" activities.

First, Fidelity has no agreements that permit customers who buy fund shares after 4 p.m. to obtain the 4 p.m. price. This is not a new policy. This is not to say that someone could not deceive the company through fraudulent acts. However, we are extremely diligent in preventing fraud from occurring in this manner - and in every other. But I underscore again that Fidelity has no so-called "agreements" that sanction illegal practices.

Second, Fidelity continues to stand on record, as we have for years, in opposition to predatory short-term trading that adversely affects shareholders in a mutual fund. Back in the 1980s, we initiated a fee - which is returned to the fund and, therefore, to investors - to discourage this activity. Further, we took the lead several years ago in developing a Fair Value Pricing Policy to prevent market timing on foreign securities in our funds. I am confident we will find other ways to make it more difficult for predatory traders to operate. However, this will only be achieved through close cooperation among regulators, legislators and the industry.

Yes, there have been unfortunate instances of unethical and illegal activity within the mutual fund industry from time to time. That is true of any industry. When this occurs, confessed or convicted offenders should be dealt with appropriately. But we are still concerned about the risk of over-regulation and the quick application of simplistic solutions to intricate problems. Every system can be improved, and we support and applaud well thought out improvements by regulators, legislators and industry representatives that achieve the common goal of building and protecting the value of investors' holdings.

For nearly 60 years, Fidelity has worked very hard to improve its products and service to justify your trust. When our family founded this company in 1946, we had only a few hundred customers. Today, we serve more than 18 million customers including individual investors and participants in retirement plans across America.

Let me close by saying that we do not take your trust in us for granted, and we realize that we must always work to improve all aspects of our service to you. In turn, we urge you to continue your active participation with your financial matters, so that your interests can be well served.

Best regards,/s/Edward C. Johnson 3d

Shareholder Expense Example

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

The Example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period (September 1, 2004 to February 28, 2005).

Actual Expenses

The first line of the table below 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 table below 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.

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.

(Amounts in thousands except ratios)

1. Significant Accounting Policies.

Fidelity Export and Multinational Fund (the fund) is a 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 financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America, which require management to make certain estimates and assumptions at the date of the financial statements. The following summarizes the significant accounting policies of the fund:

Security Valuation. Net asset value per share (NAV calculation) is calculated as of the close of business of the New York Stock Exchange, normally 4:00 p.m. Eastern time. Equity securities, including restricted securities, for which market quotations are available are valued at the last sale price or official closing price (closing bid price or last evaluated quote if no sale has occurred) on the primary market or exchange on which they trade. If prices are not readily available or do not accurately reflect fair value for a security, or if a security's value has been materially affected by events occurring after the close of the exchange or market on which the security is principally traded, that security may be valued by another method that the Board of Trustees believes accurately reflects fair value. A security's valuation may differ depending on the method used for determining value. Price movements in futures contracts and ADRs, market and trading trends, the bid/ask quotes of brokers and off-exchange institutional trading may be reviewed in the course of making a good faith determination of a security's fair value. Short-term securities with remaining maturities of sixty days or less for which quotations are not readily available are valued on the basis of amortized cost. Investments in open-end investment companies are valued at their net asset value each business day.

Foreign Currency. The fund uses foreign currency contracts to facilitate transactions in foreign-denominated securities. Losses from these transactions may arise from changes in the value of the foreign currency or if the counterparties do not perform under the contracts' terms.

Foreign-denominated assets, including investment securities, and liabilities are translated into U.S. dollars at the exchange rate at period end. Purchases and sales of investment securities, income and dividends received and expenses denominated in foreign currencies are translated into U.S. dollars at the exchange rate in effect on the transaction date.

The effects of exchange rate fluctuations on investments are included with the net realized and unrealized gain (loss) on investment securities. Other foreign currency transactions resulting in realized and unrealized gain (loss) are disclosed separately.

Semiannual Report

1. Significant Accounting Policies - continued

Investment Transactions and Income. Security transactions are accounted for as of trade date. Gains and losses on securities sold are determined on the basis of identified cost and may include proceeds received from litigation. Dividend income is recorded on the ex-dividend date, except for certain dividends from foreign securities where the ex-dividend date may have passed, which are recorded as soon as the fund is informed of the ex-dividend date. Non-cash dividends included in dividend income, if any, are recorded at the fair market value of the securities received. Distributions received on securities that represent a return of capital or capital gain are recorded as a reduction of cost of investments and/or as a realized gain. The fund estimates the components of distributions received that may be considered return of capital distributions or capital gain distributions. Large, non-recurring dividends recognized by the fund are presented separately on the Statement of Operations as "Special Dividends" and the impact of these dividends is presented in the Financial Highlights. Interest income is accrued as earned. Interest income includes coupon interest and amortization of premium and accretion of discount on debt securities. Investment income is recorded net of foreign taxes withheld where recovery of such taxes is uncertain.

Expenses. Most expenses of the trust can be directly attributed to a fund. Expenses which cannot be directly attributed are apportioned among the funds in the trust.

Income Tax Information and Distributions to Shareholders. Each year, the fund intends to qualify as a regulated investment company by distributing all of its taxable income and realized gains under Subchapter M of the Internal Revenue Code. As a result, no provision for income taxes is required in the accompanying financial statements. Foreign taxes are provided for based on the fund's understanding of the tax rules and rates that exist in the foreign markets in which it invests.

Distributions are recorded on the ex-dividend date. Income and capital gain distributions are determined in accordance with income tax regulations, which may differ from generally accepted accounting principles. 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.

Book-tax differences are primarily due to foreign currency transactions, capital loss carryforwards and losses deferred due to wash sales.

Short-Term Trading (Redemption) Fees. Shares held in the fund less than 30 days are subject to a redemption fee equal to .75% 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.

2. Operating Policies.

Repurchase Agreements. FMR has received an Exemptive Order from the Securities and Exchange Commission (the SEC) which permits the fund and other affiliated entities of FMR to transfer uninvested cash balances into joint trading accounts. These accounts are then invested in repurchase agreements that are collateralized by U.S. Treasury or Government obligations. The fund may also invest directly with institutions, in repurchase agreements that are collateralized by commercial paper obligations and corporate obligations. Collateral is held in segregated accounts with custodian banks and may be obtained in the event of a default of the counterparty. Collateral is marked-to-market daily and maintained at a value at least equal to the principal amount of the repurchase agreement (including accrued interest).

3. Purchases and Sales of Investments.

Purchases and sales of securities, other than short-term securities and U.S. government securities, aggregated $1,265,026 and $603,983, respectively.

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. The management fee is the sum of an individual fund fee rate that is based on an annual rate of .30% of the fund's average net assets and a group fee rate that averaged .27% during the period. The group fee rate is based upon the average net assets of all the mutual funds advised by FMR. The group fee rate decreases as assets under management increase and increases as assets under management decrease. For the period, the total annualized management fee rate was .58% of the fund's average net assets.

Semiannual Report

Transfer Agent Fees. Fidelity Service Company, Inc. (FSC), an affiliate of FMR, is the fund's transfer, dividend disbursing and shareholder servicing agent. FSC receives 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. For the period, the transfer agent fees were equivalent to an annualized rate of .23% of average net assets.

Accounting and Security Lending Fees. FSC maintains the fund's accounting records. The accounting fee is based on the level of average net assets for the month. Under a separate contract, FSC administers the security lending program. The security lending fee is based on the number and duration of lending transactions.

Central Funds. The fund may invest in affiliated Central Funds managed by Fidelity Investments Money Management, Inc. (FIMM), an affiliate of FMR. The Central Funds are open-end investment companies available only to investment companies and other accounts managed by FMR and its affiliates. The Central Funds seek preservation of capital and current income and do not pay a management fee. Income distributions earned by the fund are recorded as income in the accompanying financial statements and totaled $311 for the period.

Brokerage Commissions. The fund placed a portion of its portfolio transactions with brokerage firms which are affiliates of the investment adviser. The commissions paid to these affiliated firms were $21 for the period.

5. Committed Line of Credit.

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

6. Security Lending.

The fund lends portfolio securities from time to time in order to earn additional income. The fund receives collateral (in the form of U.S. Treasury obligations, letters of credit and/or cash) against the loaned securities and maintains collateral in an amount not less than 100% of the market value of the loaned securities during the period of the loan. The market value of the loaned securities is determined at the close of business of the fund and any additional required collateral is delivered to the fund on the next business day. If the borrower defaults on its obligation to return the securities loaned because of insolvency or other reasons, a fund could experience delays and costs in recovering the securities loaned or in gaining access to the collateral. Cash collateral is invested in cash equivalents. The value of loaned securities and cash collateral at period end are disclosed on the fund's Statement of Assets and Liabilities.

(Amounts in thousands except ratios)

7. Expense Reductions.

Many of the brokers with whom FMR places trades on behalf of the fund provided services to the fund in addition to trade execution. These services included payments of certain expenses on behalf of the fund totaling $250 for the period. In addition, through arrangements with the fund's 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 transfer agent expenses by $5.

8. Other.

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

Semiannual Report

Chairman's Message

(photo_of_Edward_C_Johnson_3d)

Dear Shareholder:

During the past year or so, much has been reported about the mutual fund industry, and much of it has been more critical than I believe is warranted. Allegations that some companies have been less than forthright with their shareholders have cast a shadow on the entire industry. I continue to find these reports disturbing, and assert that they do not create an accurate picture of the industry overall. Therefore, I would like to remind everyone where Fidelity stands on these issues. I will say two things specifically regarding allegations that some mutual fund companies were in violation of the Securities and Exchange Commission's forward pricing rules or were involved in so-called "market timing" activities.

First, Fidelity has no agreements that permit customers who buy fund shares after 4 p.m. to obtain the 4 p.m. price. This is not a new policy. This is not to say that someone could not deceive the company through fraudulent acts. However, we are extremely diligent in preventing fraud from occurring in this manner - and in every other. But I underscore again that Fidelity has no so-called "agreements" that sanction illegal practices.

Second, Fidelity continues to stand on record, as we have for years, in opposition to predatory short-term trading that adversely affects shareholders in a mutual fund. Back in the 1980s, we initiated a fee - which is returned to the fund and, therefore, to investors - to discourage this activity. Further, we took the lead several years ago in developing a Fair Value Pricing Policy to prevent market timing on foreign securities in our funds. I am confident we will find other ways to make it more difficult for predatory traders to operate. However, this will only be achieved through close cooperation among regulators, legislators and the industry.

Yes, there have been unfortunate instances of unethical and illegal activity within the mutual fund industry from time to time. That is true of any industry. When this occurs, confessed or convicted offenders should be dealt with appropriately. But we are still concerned about the risk of over-regulation and the quick application of simplistic solutions to intricate problems. Every system can be improved, and we support and applaud well thought out improvements by regulators, legislators and industry representatives that achieve the common goal of building and protecting the value of investors' holdings.

For nearly 60 years, Fidelity has worked very hard to improve its products and service to justify your trust. When our family founded this company in 1946, we had only a few hundred customers. Today, we serve more than 18 million customers including individual investors and participants in retirement plans across America.

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, 2004 to February 28, 2005).

Actual Expenses

The first line of the table below 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.

Hypothetical Example for Comparison Purposes

The second line of the table below 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.

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

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

BTotal returns for periods of less than one year are not annualized.

CTotal returns would have been lower had certain expenses not been reduced during the periods shown.

DCalculated based on average shares outstanding during the period.

EExpense ratios reflect operating expenses of the fund. Expenses before reductions do not reflect amounts reimbursed by the investment adviser or reductions from brokerage service arrangements or other expense offset arrangements and do not represent the amount paid by the fund during periods when reimbursements or reductions occur. Expenses net of any voluntary waivers reflect expenses after reimbursement by the investment adviser but prior to reductions from brokerage service arrangements or other expense offset arrangements. Expenses net of all reductions represent the net expenses paid by the fund.

FEffective September 1, 2001, the fund adopted the provisions of the AICPA Audit and Accounting Guide for Investment Companies and began amortizing premium and discount on all debt securities. Per-share data and ratios for periods prior to adoption have not been restated to reflect this change.

GAmount represents less than $.001 per share.

Notes to Financial Statements

For the period ended February 28, 2005 (Unaudited)

1. Significant Accounting Policies.

Spartan 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. 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. 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 income fund and the money market fund:

Security Valuation. Net asset value per share (NAV calculation) is calculated as of the close of business of the New York Stock Exchange, normally 4:00 p.m. Eastern time. Debt securities, including restricted securities, are valued on the basis of information provided by a pricing service. Pricing services use valuation matrices that incorporate both dealer-supplied valuations and valuation models. If prices are not readily available or do not accurately reflect fair value for a security, or if a security's value has been materially affected by events occurring after the close of the exchange or market on which the security is principally traded, that security may be valued by another method that the Board of Trustees believes accurately reflects fair value. A security's valuation may differ depending on the method used for determining value. Price movements in futures contracts and ADRs, market and trading trends, the bid/ask quotes of brokers and off-exchange institutional trading may be reviewed in the course of making a good faith determination of a security's fair value. Short-term securities with remaining maturities of sixty days or less for which quotations are not readily available are valued on the basis of amortized cost. Investments in open-end investment companies are valued at their net asset value each business day.

As permitted under Rule 2a-7 of the 1940 Act, and certain conditions therein, securities owned by the money market fund are valued initially at cost and thereafter assume a constant amortization to maturity of any discount or premium.

Investment Transactions and Income. Security transactions are accounted for as of trade date. 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.

1. Significant Accounting Policies - continued

Expenses. Most expenses of each trust can be directly attributed to a fund. Expenses which cannot be directly attributed are apportioned among the funds in the trust.

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

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

Book-tax differences are primarily due to market discount and losses deferred due to wash sales and futures transactions.

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:

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 Fidelity Management & Research Company (FMR), are retained by the fund and accounted for as an addition to paid in capital.

Semiannual Report

2. Operating Policies.

Delayed Delivery Transactions and When-Issued Securities. Each 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 each applicable fund's Schedule of Investments. Each fund may receive compensation for interest forgone in the purchase of a delayed delivery or when-issued security. With respect to purchase commitments, each 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.

3. Purchases and Sales of Investments.

Purchases and sales of securities, other than short-term securities and U.S. government securities, for the income fund aggregated $16,655,670 and $3,339,944, respectively.

4. 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 non-interested Trustees and certain exceptions such as interest expense. 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 non-interested Trustees. Each fund's management fee is equal to the following annual rate of average net assets:

.55%

|

Fidelity Arizona Municipal Money Market Fund

.50%

Central Funds. The funds may invest in affiliated Central Funds managed by Fidelity Investments Money Management, Inc. (FIMM), an affiliate of FMR. The Central Funds are open-end investment companies available only to investment companies and other accounts managed by FMR and its affiliates. The Central Funds seek preservation of capital and current income and do not pay a management fee. Income distributions earned by the funds are recorded as income in the accompanying financial statements. Distributions from the Central Funds are noted in the table below:

Notes to Financial Statements (Unaudited) - continued

5. 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 included 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 each applicable fund's custodian and transfer agent, 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:

Spartan Arizona Municipal Income Fund

$18,220

Fidelity Arizona Municipal Money Market Fund

42,665

7. 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.

Chairman's Message

(photo_of_Edward_C_Johnson_3d)

Dear Shareholder:

During the past year or so, much has been reported about the mutual fund industry, and much of it has been more critical than I believe is warranted. Allegations that some companies have been less than forthright with their shareholders have cast a shadow on the entire industry. I continue to find these reports disturbing, and assert that they do not create an accurate picture of the industry overall. Therefore, I would like to remind everyone where Fidelity stands on these issues. I will say two things specifically regarding allegations that some mutual fund companies were in violation of the Securities and Exchange Commission's forward pricing rules or were involved in so-called "market timing" activities.

First, Fidelity has no agreements that permit customers who buy fund shares after 4 p.m. to obtain the 4 p.m. price. This is not a new policy. This is not to say that someone could not deceive the company through fraudulent acts. However, we are extremely diligent in preventing fraud from occurring in this manner - and in every other. But I underscore again that Fidelity has no so-called "agreements" that sanction illegal practices.

Second, Fidelity continues to stand on record, as we have for years, in opposition to predatory short-term trading that adversely affects shareholders in a mutual fund. Back in the 1980s, we initiated a fee - which is returned to the fund and, therefore, to investors - to discourage this activity. Further, we took the lead several years ago in developing a Fair Value Pricing Policy to prevent market timing on foreign securities in our funds. I am confident we will find other ways to make it more difficult for predatory traders to operate. However, this will only be achieved through close cooperation among regulators, legislators and the industry.

Yes, there have been unfortunate instances of unethical and illegal activity within the mutual fund industry from time to time. That is true of any industry. When this occurs, confessed or convicted offenders should be dealt with appropriately. But we are still concerned about the risk of over-regulation and the quick application of simplistic solutions to intricate problems. Every system can be improved, and we support and applaud well thought out improvements by regulators, legislators and industry representatives that achieve the common goal of building and protecting the value of investors' holdings.

For nearly 60 years, Fidelity has worked very hard to improve its products and service to justify your trust. When our family founded this company in 1946, we had only a few hundred customers. Today, we serve more than 18 million customers including individual investors and participants in retirement plans across America.

Let me close by saying that we do not take your trust in us for granted, and we realize that we must always work to improve all aspects of our service to you. In turn, we urge you to continue your active participation with your financial matters, so that your interests can be well served.

Best regards,/s/Edward C. Johnson 3d

Shareholder Expense Example

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

The Example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period (September 1, 2004 to February 28, 2005).

Actual Expenses

The first line of the table below 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 table below 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.

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

Duration shows how much a bond fund's price fluctuates with changes in comparable interest rates.

Notes to Financial Statements

For the period ended February 28, 2005 (Unaudited)

1. Significant Accounting Policies.

Spartan Maryland Municipal Income Fund (the fund) is a 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. The financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America, which require management to make certain estimates and assumptions at the date of the financial statements. The following summarizes the significant accounting policies of the fund:

Security Valuation. Net asset value per share (NAV calculation) is calculated as of the close of business of the New York Stock Exchange, normally 4:00 p.m. Eastern time. Debt securities, including restricted securities, are valued on the basis of information provided by a pricing service. Pricing services use valuation matrices that incorporate both dealer-supplied valuations and valuation models. If prices are not readily available or do not accurately reflect fair value for a security, or if a security's value has been materially affected by events occurring after the close of the exchange or market on which the security is principally traded, that security may be valued by another method that the Board of Trustees believes accurately reflects fair value. A security's valuation may differ depending on the method used for determining value. Price movements in futures contracts and ADRs, market and trading trends, the bid/ask quotes of brokers and off-exchange institutional trading may be reviewed in the course of making a good faith determination of a security's fair value. Short-term securities with remaining maturities of sixty days or less for which quotations are not readily available are valued on the basis of amortized cost. Investments in open-end investment companies are valued at their net asset value each business day.

Investment Transactions and Income. Security transactions are accounted for as of trade date. 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 the funds in the trust.

Income Tax Information and Distributions to Shareholders. Each year, the fund intends to qualify as a regulated investment company by distributing all of its taxable income and realized gains under Subchapter M of the Internal Revenue Code. As a result, no provision for income taxes is required in the accompanying financial statements. Dividends are declared daily and paid monthly from net investment income. Distributions from realized gains, if any, are recorded on the ex-dividend date. Income and

Semiannual Report

Notes to Financial Statements (Unaudited) - continued

Income Tax Information and Distributions to Shareholders - continued

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. Book-tax differences are primarily due to market discount and 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

$4,478,449

Unrealized depreciation

(229,856)

Net unrealized appreciation (depreciation)

$4,248,593

Cost for federal income tax purposes

$98,247,063

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.

2. 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

Delayed Delivery Transactions and When-Issued Securities - continued

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.

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

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

Swaps are marked-to-market daily based on dealer-supplied valuations and changes in value are recorded as unrealized appreciation (depreciation). Gains or losses are realized upon early termination of the swap agreement. Collateral, in the form of cash or securities, may be required to be held in segregated accounts with the fund's custodian in compliance with swap contracts.

3. Purchases and Sales of Investments.

Purchases and sales of securities, other than short-term securities and U.S. government securities, aggregated $15,402,420 and $8,805,144, respectively.

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 non-interested Trustees and certain exceptions such as interest expense. 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 non-interested Trustees.

5. Committed Line of Credit.

The fund participates with other funds managed by FMR in a $4.2 billion credit facility (the "line of credit") to be utilized for temporary or emergency purposes to fund shareholder redemptions or for other short-term liquidity purposes. The fund has agreed to

pay commitment fees on its pro rata portion of the line of credit, which is included 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 $18,738.

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.
