Wankinco River
The Wankinco River is a  river in eastern Massachusetts, United States.  It is a tributary of the Wareham River, which drains into Buzzards Bay.

The river originates at East Head Reservoir, a pond in the Myles Standish State Forest, and flows southwards through various impoundments and cranberry bogs to join the Agawam River near the center of Wareham, Massachusetts, after which it forms the Wareham River, forming Wareham's main harbor with a depth of about . During a portion of its course, it serves as the boundary between Carver and Plymouth, Massachusetts.
