The Chigoubiche Lake is the main freshwater body at the head of the Chigoubiche River (slope of the Ashuapmushuan River), flowing into the unorganized territory of Lac-Ashuapmushuan, Quebec, in the Regional County Municipality (MRC) Le Domaine-du-Roy, in the administrative region of Saguenay-Lac-Saint-Jean, in the province of Quebec, in Canada.

Located halfway between Saint-Félicien, Quebec and Chibougamau, Lake Chigoubiche is the largest body of water in the Ashuapmushuan Wildlife Reserve.

The surface of Lake Chigoubiche is usually frozen from early November to mid-May, however safe ice circulation is generally from mid-November to mid-April.

During his 1732 expedition, surveyor Joseph-Laurent Normandin noted this toponym which derives from the Innu term "ushukupish", meaning "the place where les Betsis (Saw-Bees) brood".

Today, in addition to still hunting in this territory, nature lovers also practice sport fishing, including pike and walleye.
