Les Chenaux (French pronunciation: [le ʃəno], meaning the channels in French) is a regional county municipality in central Quebec, Canada, in the Mauricie region.

It has a land area of 872.04 square kilometres (336.70 sq mi) and a population of 17,865 inhabitants in the Canada 2011 Census.

The "Les Chenaux" RCM is an area east of Trois-Rivières, located between the villages of Champlain and Sainte-Anne-de-la-Pérade on north shore of St. Lawrence River.

The RCM was created in 2002, when the area was realigned to make way for the amalgamations of nearby Trois-Rivières and Shawinigan.

The remaining municipalities were grouped into a new regional county called Les Chenaux.
