The Financial District of Lower Manhattan, also known as FiDi, is a neighborhood located on the southern tip of Manhattan island in New York City. It is bounded by the West Side Highway on the west, Chambers Street and City Hall Park on the north, Brooklyn Bridge on the northeast, the East River to the southeast, and The Battery on the south. The City of New York was created in the Financial District in 1624, and the neighborhood roughly overlaps with the boundaries of the New Amsterdam settlement in the late 17th century. The district comprises the offices and headquarters of many of the city's major financial institutions, including the New York Stock Exchange and the Federal Reserve Bank of New York

The Financial District encompasses roughly the area south of City Hall Park in Lower Manhattan but excludes Battery Park and Battery Park City. The former World Trade Center complex was located in the neighborhood until the September 11, 2001 attacks; the neighborhood includes the successor One World Trade Center. 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 Financial District is part of Manhattan Community Board 1, which also includes five other neighborhoods (Battery Park City, Civic Center, Greenwich South, Seaport, and Tribeca).
