Étang de Soulcem is a large artificial lake in the Pyrenees mountains in Ariège, France. It is at an elevation of 1570 m and is used for hydroelectricity, generating 62 GWh/year. The lake, which has a surface area of 0.91 km², was formed following the construction by Électricité de France of a dam across the northern end of the Vicdessos valley in 1980–1983.
