The Coulonge River (English: /kuːˈlɒndʒ/;[4] French: [kulɔ̃ʒ]) is a predominantly wilderness river in western Quebec, Canada.[5]
A popular river for whitewater canoeing enthusiasts, it is often grouped together with the Dumoine and Noire Rivers as three of a kind. The three rivers share the same watershed, and have similar whitewater characteristics.[6] All three empty into the Ottawa River within a distance of 105 kilometers (65 mi) from one another.
