Frenchman Lake is a reservoir located in southeastern Plumas County, California. It was created by the damming of Little Last Chance Creek in 1961, as part of the California State Water Project. It was named after its tributary Frenchman Creek, which in turn was named after Claude Francois Seltier, a French immigrant who settled in the area in 1858.

It is a rock-fill and earthen dam 129 feet (39 m) high, with a length of 720 feet (220 m) at its crest. Normal water storage in the reservoir is 55,477 acre-feet (68,430,000 m).
