Frenchman River, Brook in Saskatchewan, Canada

Frenchman River is a waterway in Saskatchewan and Montana that stretches across approximately 341 kilometers before joining the Milk River near Saco. The channel winds through varied terrain and creates several meanders, particularly where it flows through Grasslands National Park.

The origin of the name is uncertain: both Métis and francophone settlers lived along its banks around the turn of the 20th century, and in Montana the river is called Frenchman Creek. The Frenchman Formation, a stratigraphic unit of the Western Canadian Sedimentary Basin, is named after the river.
