The Whitemouth River is a scenic waterway flowing through Manitoba, Canada, eventually joining the Winnipeg River at Whitemouth Falls. The river is characterized by a mix of moving water environments, including numerous rapids that attract whitewater paddlers alongside anglers. Twelve navigable whitewater features run along the river, most rated Class I or II, with Cooks Falls and Neva Falls presenting more challenging conditions. The river is notable not only for its fishing opportunities but also for its ecological significance, harboring rare and at-risk fish species found almost nowhere else in Canada.
