The Whitman River is an 8.4-mile-long (13.5 km) river in Massachusetts that flows through Ashburnham, Westminster and Fitchburg. It arises from Lake Wampanoag in Ashburnham, travels through a couple of ponds in Westminster, and ultimately joins Phillips Brook in Fitchburg to form the North Nashua River, a principal tributary of the Nashua River.
