Mascoma Lake is a 1,165-acre (4.71 km2),lake in western New Hampshire, United States. Most of the lake is located within the town of Enfield, while a small portion is within the city of Lebanon, where it drains into the Mascoma River, a tributary of the Connecticut River.

The lake's general trend is from southeast to northwest, with the outlet at the northwestern end. The Mascoma River enters the lake near its halfway point, from the northeastern side, at the town center of Enfield. The southeastern end of the lake is fed by the Knox River. The lake's average depth is 30 feet (9.1 m) with a maximum depth of 68 feet (21 m).

The lake freezes during winter and is stable enough to be walked upon. Ice fishing is popular on the lake. During the winter months, ice shacks dot the frozen surface. The lake is stocked with trout by the New Hampshire Fish and Game department.

Mascoma Lake has a spring cyanobacteria bloom. In June 2009 the State of New Hampshire discouraged people from recreation in some areas of the lake because of the bloom.However, the lake is considered safe for swimming, and the town of Enfield maintains a public beach with a lifeguard on the lake.
