The Bronx River, approximately 24 miles (39 km) long, flows through southeast New York in the United States and drains an area of 38.4 square miles (99 km²). It is named after colonial settler Jonas Bronck. The Bronx River is the only fresh water river in New York City.

It originally rose in what is now the Kensico Reservoir, in Westchester County north of New York City. With the construction of the Kensico Dam in 1885, however, the river was cut off from its natural headwaters and today a small tributary stream serves as its source. The Bronx River flows south past White Plains, then south-southwest through the northern suburbs, passing through Edgemont, Tuckahoe, Eastchester, and Bronxville. It forms the border between the large cities of Yonkers and Mount Vernon, and flows into the northern end of The Bronx, southward through Bronx Park, New York Botanical Garden, and the Bronx Zoo and continues through urbanized areas of the South Bronx where it divides East Bronx from West Bronx. It empties into the East River, a tidal strait connected to Long Island Sound, between the Soundview and Hunts Point neighborhoods.
