The Roeliff Jansen Kill is a major tributary to the Hudson River. Roeliff Jansen Kill was the traditional boundary between the Native American Mahican and Wappinger tribes.

Its source is in the town of Austerlitz, New York, and its mouth is at the Hudson River at Linlithgo in the town of Livingston. The stream flows for 56.2 miles (90.4 km) through Dutchess and Columbia counties before entering the Hudson River about 5 miles (8.0 km) south of Hudson.

Most of the watershed lies in Columbia County, although parts of the northern Dutchess County towns of North East, Stanford, Pine Plains, Milan, and Red Hook are within the stream's watershed of approximately 212 square miles (550 km2). A major tributary is Shekomeko Creek.
