The Ouiatchouaniche River is a tributary of Lac Saint-Jean, flowing successively in the unorganized territory of Lac-Ashuapmushuan, the municipality of Sainte-Hedwidge and the city of Roberval, in the Le Domaine-du-Roy Regional County Municipality, in the administrative region of Saguenay–Lac-Saint-Jean, in the province of Quebec, in Canada.
The upper part of the Ouiatchouaniche river valley is served by forest roads.
Forestry is the main economic activity in the upper and intermediate part of this valley; agriculture, in the lower part, except the urban area near the mouth.
The surface of the Ouiatchouaniche River is usually frozen from the beginning of December to the end of March, except the rapids areas; however, traffic on the ice is generally safe from mid-December to mid-March.
