The East River is a saltwater tidal estuary or strait in New York City. The waterway, which is not a river despite its name, connects Upper New York Bay on its south end to Long Island Sound on its north end. It separates Long Island, with the boroughs of Brooklyn and Queens, from Manhattan Island, and from the Bronx on the North American mainland. The East River forms the eastern boundary of Manhattan Island, whereas the island's western boundary is formed by the Hudson River.
