The Mitis River (French: Rivière Mitis) is a salmon river in the Bas-Saint-Laurent region of Quebec, Canada. It flows to the south shore of the Saint Lawrence River. There are two hydroelectric dams on the river at a point where a waterfall used to prevent salmon from going further upstream. A system to capture and transport salmon upstream was installed in 1965, and the river now has a healthy salmon population along its whole length.
