The Bronx River (/brɒŋks/), is a river that is approximately 24 miles (39 km) long,^[4] and flows through southeastern New York in the United States and drains an area of 38.4 square miles (99 km²).^[4] It is named after colonial settler Jonas Bronck.

It originally rose in what is now the Kensico Reservoir, in Westchester County north of New York City, on a hill about 650 feet above sea level in what is now New Castle, New York. The river originated in an area the Weckquasgeek called Quaropes, which means White Marshes. It was fed by the Fulton Brook, Manhattan Park Brook, Davis Brook, and Tompkins Brook.^[5] 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 originating from the reservoir serves as its source. The Bronx River flows south past White Plains, then south-southwest through the northern suburbs in New York, passing through Edgemont, Tuckahoe, Eastchester, and Bronxville. In the area known as the Aquehung, it is fed by Harts Brook and the north and south Fox Meadow Brooks. At Tuckahoe, it is fed by Troublesome Brook. At Bronxville, it is fed by Sprain Brook, its longest tributary system, which originates at Greenburgh Town Park.^[6]

The river forms the border between the large cities of Yonkers and Mount Vernon, and flows into the northern end of The Bronx, where it divides East Bronx from West Bronx, southward through Bronx Park, New York Botanical Garden, and the Bronx Zoo and continues through neighborhoods of the South Bronx. It empties into the East River, a tidal strait connected to Long Island Sound, between the Soundview and Hunts Point neighborhoods.
