Wall Street is the financial district of New York City. It is also the name of the street running from Broadway to South Street on the East River. Over time Wall Street came to signify a geographic location encompassing a commercial downtown Manhattan neighborhood as well as signifying the historical financial center of the United States. The term has become a metonym signifying New York-based financial interests. It is the first permanent home of the New York Stock Exchange, the world’s largest stock exchange by market capitalization of its listed companies. Anchored by Wall Street, New York City is one of the principal financial centres of the world.

Several major U.S. stock and other exchanges have headquarters on Wall Street and in the Financial District, including the NYSE, NASDAQ, AMEX, NYMEX, and NYBOT.
Wall Street is important in a nation such as the United States in which former president Calvin Coolidge once remarked "The business of America is business" and in which rising stock markets are called bulls and falling markets are called bears.

Wall Street est le nom d’une rue située dans le sud de l’arrondissement de Manhattan à New York (États-Unis). Wall Street part à l’est de Broadway en direction de l’East River jusqu’à South Street ; elle traverse une partie du Financial District, un quartier d’affaires.

Au xviie siècle, elle formait la limite nord de la colonie de Nouvelle-Amsterdam appartenant aux Néerlandais. Ceux-ci y avaient construit un mur fait de rondins de bois et de terre, pour se protéger des indiens Lenape et des colons britanniques. Le mur ne fut jamais mis à l’épreuve des batailles mais fut démoli par les Anglais en 1699.
