Assawompset Pond is a reservoir/pond within the towns of Lakeville and Middleboro, in southeastern Massachusetts.

It is known in Wampanoag as Place of the White Stones and is host for the largest alewife (herring) run in the eastern seaboard.

In the early spring the Nemasket River runs black with fish heading for the spawning grounds.

King Philip's War began with the discovery of John Sassamon's body and the subsequent trial of his suspected murderers.

The pond was dammed in 1894 at the Nemasket River, which raised the water level about five feet (1.5 m).
