Spuyten Duyvil Creek (/ˈspaɪtən ˈdaɪvəl/) is a short tidal estuary in New York City connecting the Hudson River to the Harlem River Ship Canal and then on to the Harlem River. The confluence of the three water bodies separate the island of Manhattan from the Bronx and the rest of the mainland. Once a distinct, turbulent waterway between the Hudson and Harlem rivers, the creek has been subsumed by the modern ship canal.
The Bronx neighborhood of Spuyten Duyvil lies to the north of the estuary creek, and the adjacent Manhattan neighborhood of Marble Hill lies to the north of the Ship Canal.
