Fidelity New York Municipal Money Market Fund

Fund Summary

Fund:
Fidelity^®New York Municipal Money Market Fund

Investment Objective

The fund seeks as high a level of current income exempt from federal income tax and New York State and City personal income taxes as is consistent with preservation of capital.

Fee Table

The following table describes the fees and expenses that may be incurred when you buy and hold shares of the fund.

Shareholder fees
(fees paid directly from your investment)

Shareholder Fees (USD $)	Fidelity New York Municipal Money Market Fund Class: Fidelity New York Municipal Money Market Fund
Shareholder fees (fees paid directly from your investment)	none

Annual fund operating expenses
(expenses that you pay each year as a % of the value of your investment)

Annual Fund Operating Expenses	Fidelity New York Municipal Money Market Fund Class: Fidelity New York Municipal Money Market Fund
Management fee	0.37%
Distribution and/or Service (12b-1) fees	none
Other expenses	0.13%
Total annual fund operating expenses	0.50%

This example helps compare the cost of investing in the fund with the cost of investing in other mutual funds.

Let's say, hypothetically, that the annual return for shares of the fund is 5% and that your shareholder fees and the annual operating expenses for shares of the fund are exactly as described in the fee table. This example illustrates the effect of fees and expenses, but is not meant to suggest actual or expected fees and expenses or returns, all of which may vary. For every $10,000 you invested, here's how much you would pay in total expenses if you sell all of your shares at the end of each time period indicated:

Expense Example (USD $)	Fidelity New York Municipal Money Market Fund Class: Fidelity New York Municipal Money Market Fund
1 year	51
3 years	160
5 years	280
10 years	628

Principal Investment Strategies

• Normally investing in municipal money market securities.
• Normally investing at least 80% of assets in municipal securities whose interest is exempt from federal and New York State and City personal income taxes.
• Potentially investing up to 20% of assets in municipal securities whose interest is subject to New York State and City personal income taxes.
• Potentially investing more than 25% of total assets in municipal securities that finance similar types of projects.
• Investing in compliance with industry-standard regulatory requirements for money market funds for the quality, maturity, and diversification of investments.

Principal Investment Risks

• Municipal Market Volatility. The municipal market is volatile and can be significantly affected by adverse tax, legislative, or political changes and the financial condition of the issuers of municipal securities.
• Interest Rate Changes. Interest rate increases can cause the price of a money market security to decrease.
• Foreign Exposure. Entities providing credit support or a maturity-shortening structure that are located in foreign countries can be affected by adverse political, regulatory, market, or economic developments in those countries.
• Geographic Concentration. Unfavorable political or economic conditions within New York can affect the credit quality of issuers located in that state.
• Issuer-Specific Changes. A decline in the credit quality of an issuer or a provider of credit support or a maturity-shortening structure for a security can cause the price of a money market security to decrease.

An investment in the fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Although the fund seeks to preserve the value of your investment at $1.00 per share, it is possible to lose money by investing in the fund.

This example helps compare the cost of investing in the fund with the cost of investing in other mutual funds.

Let's say, hypothetically, that the annual return for shares of the fund is 5% and that your shareholder fees and the annual operating expenses for shares of the fund are exactly as described in the fee table. This example illustrates the effect of fees and expenses, but is not meant to suggest actual or expected fees and expenses or returns, all of which may vary. For every $10,000 you invested, here's how much you would pay in total expenses if you sell all of your shares at the end of each time period indicated:

Principal Investment Strategies

• Normally investing in municipal money market securities.
• Normally investing at least 80% of assets in municipal securities whose interest is exempt from federal and New York State and City personal income taxes.
• Potentially investing up to 20% of assets in municipal securities whose interest is subject to New York State and City personal income taxes.
• Normally not investing in municipal securities whose interest is subject to the federal alternative minimum tax.
• Potentially investing more than 25% of total assets in municipal securities that finance similar types of projects.
• Investing in compliance with industry-standard regulatory requirements for money market funds for the quality, maturity, and diversification of investments.

Principal Investment Risks

• Municipal Market Volatility. The municipal market is volatile and can be significantly affected by adverse tax, legislative, or political changes and the financial condition of the issuers of municipal securities.
• Interest Rate Changes. Interest rate increases can cause the price of a money market security to decrease.
• Foreign Exposure. Entities providing credit support or a maturity-shortening structure that are located in foreign countries can be affected by adverse political, regulatory, market, or economic developments in those countries.
• Geographic Concentration. Unfavorable political or economic conditions within New York can affect the credit quality of issuers located in that state.
• Issuer-Specific Changes. A decline in the credit quality of an issuer or a provider of credit support or a maturity-shortening structure for a security can cause the price of a money market security to decrease.

An investment in the fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Although the fund seeks to preserve the value of your investment at $1.00 per share, it is possible to lose money by investing in the fund.
