The Financial District of New York City is a neighborhood on the southernmost section of the borough of Manhattan which comprises the offices and headquarters of many of the city's major financial institutions, including the New York Stock Exchange. The neighborhood was held by the World Trade Center until the September 11, 2001 terrorist attacks. The neighborhood is roughly coterminous with the boundaries of the New Amsterdam settlement in the late 17th century, and has a population of about 30,000.

As a district, it encompasses roughly the area south of City Hall Park but excluding Battery Park and Battery Park City. The heart of the Financial District is often considered to be the corner of Wall Street and Broad Street, both of which are contained entirely within the district.

The Fulton Fish Market used to be contained in the southern end of the Financial District until the company was moved to Hunts Point in The Bronx.

Federal Hall National Memorial, on the site of the first US Capitol and the inauguration of George Washington as the first President of the United States, is located at the corner of Wall Street and Nassau Street. Although becoming more residential, as evidenced by more apartments within the district itself, as well as several hotels, the neighborhood is considered to be primarily a destination for daytime traders and office workers from around New York City and the surrounding areas.
