The Agawam River is a 10.7-mile-long (17.2 km) stream in southeastern Massachusetts, USA, that is part of the Wareham River estuary watershed. The Agawam River is named in honor of the peaceful Native Americans that helped the Massachusetts Bay Colony establish its first Connecticut River Valley settlement at Springfield, Massachusetts in 1636, and helped it to flourish while many of the Connecticut Colony settlements south of Springfield were attacked or destroyed by more war-like Native American tribes.

The Agawam River iver originates at Halfway Pond, east of the Myles Standish State Forest in Plymouth, flows southwest through Glen Charlie Pond and East Wareham, and drains into the Wareham River near the center of Wareham. As the estuary's major contributor of nutrients and fresh water, the Agawam was one of the most important herring rivers in Massachusetts. Its herring runs have been operated by European settlers since 1632 and were officially established as a managed run in 1832.
