The Saw Kill is a 14.3-mile-long (23.0 km) tributary of the Hudson River, called the Metambesem by the Algonquin people of the area and sometimes called Sawkill Creek today. It rises in the town of Milan and drains a 22-square-mile (57 km2) area of northwestern Dutchess County, New York, that includes most of the town of Red Hook to the west and part of Rhinebeck to Red Hook's south.
