The Pipmuacan Reservoir (French: Réservoir Pipmuacan) is a man-made lake on the boundary of the Saguenay–Lac-Saint-Jean and Côte-Nord regions of Quebec, Canada, about 130 kilometres (81 mi) north of Chicoutimi. It is used to control the flow for downstream hydro-electric generating stations on the Betsiamites River and, through Lake Pamouscachiou, also on the Shipshaw River.
