The Coquille River is a tributary of Nicabau Lake, flowing into the unorganized territory of Lac-Ashuapmushuan, Quebec, into the Regional County Municipality (RCM) of Le Domaine-du-Roy, in the administrative region of Saguenay-Lac-Saint-Jean, in Quebec, in Canada.
This river crosses successively the cantons of Charron and Ducharme. This river is part of the Ashuapmushuan Wildlife Reserve. Forestry is the main economic activity of this valley; recreational tourism activities, second.
