The Harlem River is an 8-mile (13 km) tidal strait in New York, United States, flowing between the Hudson River and the East River and separating the island of Manhattan from the Bronx on the New York mainland.

The northern stretch, also called the Spuyten Duyvil ("spewing devil") Creek, has been significantly altered for navigation purposes. Originally it curved around the north of Marble Hill, but in 1895 the Harlem Ship Canal was dug between Manhattan and Marble Hill, and in 1914 the original course was filled in.
