The Rouge River (French: rivière Rouge, pronounced [ʁivjɛʁ ʁuʒ], lit.'Red River') is a river flowing in the Laurentides, in the municipality of Grenville-sur-la-Rouge, in the Argenteuil Regional County Municipality, in the administrative region of Laurentides, in the west of Quebec, in western Quebec, Canada.

This 161 kilometres (100 mi) river takes its source at Lac de la Fougère and flows south to empty into the Ottawa River near Pointe-au-Chêne and flows north of Mont Tremblant, of which it is a tributary of the left bank. It is in the Laurentides, about halfway between Ottawa and Montreal. Its name is derived from the reddish tint of its sandbanks.

The river is a popular destination for whitewater rafting. Its last 10 kilometres are renowned for rafting. It is the main body of water in an area comprising hills, valleys, lakes, and waterfalls.
