The Caupichigau River is a tributary of the La Trève River, flowing into Regional County Municipality (RCM) of Eeyou Istchee James Bay (municipality), within the administrative region of Nord-du-Québec, Canadian province of Quebec, in Canada.

The course of the river Caupichigau crosses successively the cantons of Berey and Daine.
