Wall Street is a thoroughfare in lower Manhattan island, New York City, USA. It runs east from Broadway downhill to South Street on the East River, through the historical center of the Financial District. Wall Street was the first permanent home of the New York Stock Exchange, over time Wall Street became the name of the surrounding geographic neighborhood. Wall Street is also shorthand (or a metonym) for "influential financial interests" in the U.S. as well as for the financial industry in the New York City area.

Several major U.S. stock and other exchanges remain headquartered on Wall Street and in the Financial District, including the NYSE, NASDAQ, AMEX, NYMEX, and NYBOT. Many New York-based financial firms are no longer headquartered on Wall Street, but are in midtown Manhattan, the outer boroughs of the city, Long Island, Westchester County, Fairfield County, Connecticut, or New Jersey.
