Lac de Mauvoisin is a reservoir in the canton of Valais, Switzerland. The reservoir is formed by the Mauvoisin Dam, which is 250 m high. The dam is currently the 11th highest in the world, and the 6th highest arch dam. It was built in 1951–1957, and raised by 13.5 m in 1991.

The reservoir lies in the upper Val de Bagnes, between the massif of the Grand Combin, one of the highest mountains of the Alps, and La Ruinette. The highest peak visible from the lake is the Combin de la Tsessette (4,135 m).
