Upper New York Bay

New York Harbor is a tidal body of water forming the upper part of New York Bay within the New York–New Jersey Harbor Estuary. Located on the East Coast of the United States at the mouth of the Hudson River, it is connected to Long Island Sound by the East River, which despite its name is actually a tidal strait. New York Harbor is generally synonymous with Upper New York Bay, which is enclosed by the New York City boroughs of Manhattan, Brooklyn, and Staten Island and the Hudson County, New Jersey, municipalities of Jersey City and Bayonne, although in colloquial usage it can sometimes expand to cover Upper and Lower New York Bay. New York Harbor is one of the largest natural harbors in the world.
