The Chaudiere River is a tributary of the Normandin River, flowing into the unorganized territory of Lac-Ashuapmushuan, Quebec, into the Regional County Municipality (MRC) of Le Domaine-du-Roy, in the administrative region of Saguenay-Lac-Saint-Jean, Quebec, Canada.

The Chaudière River flows in the townships of Vimont, Mance, Mignault and Aigremont.

The route 167 (northwesterly) connecting Chibougamau to Saint-Félicien, Quebec intersects the lower (i.e., southerly) section of the river Chaudière.

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

The Chaudière River originates at the mouth of lake Chaudière (length: 3.2 kilometres (2.0 mi); width: 1.5 kilometres (0.93 mi); altitude: 422 metres (1,385 ft)) in the canton of Mance.
