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.

Both Roeliff Jansen Kill and Roeliff Jansen Park outside Hillsdale, NY were named after Roeliff Jansen.  Roeloff Jansen (1602-1637) was born on the island of Marstrand in Bohuslän, Norway. In 1623, Jansen married Anneke Jans (1605-1663) who was from Flekkeroy, in Vest Agder, Norway. Following the birth of their first three children, they emigrated to New Netherland in 1630. The couple settled in first Rensselaerwyck near what is now Albany, New York, where Jansen had an engagement as a tenant farmer for Kiliaen Van Rensselaer. About 1634, he moved his family to New Amsterdam where he acquired a 62 acre farm on Manhattan Island, today in the Tribeca area of lower Manhattan. After his death, his widow married Domine Everardus Bogardus.
