The Frenchman River, (Gros Ventre: níhʔɔɔtóóúníícááh, lit. 'white person river'[1]), also known locally as the Whitemud River, is a river in Saskatchewan, Canada and Montana, United States.[2] It is a tributary of the Milk River, itself a tributary of the Missouri and in turn a part of the Mississippi River watershed that flows to the Gulf of Mexico.[2]

The name origin is uncertain, although both Métis and francophone settlers inhabited its banks at the turn of the 20th century. The Frenchman Formation, a stratigraphical unit of the Western Canadian Sedimentary Basin, was named for the river.
The headwaters are found in Cypress Lake, in the Cypress Hills, at an elevation of 975 meters (3,199 ft). It flows east towards Eastend, then turns south-east. Various reservoirs are built on its course (Eastend Reservoir, Huff Lake, Newton Lake) and the river is used extensively for irrigation. The river becomes meandered as it flows through the Grasslands National Park, then turns south into Montana, where it flows into the Milk River, in Phillips County, Montana, north of Saco.
The fish species include walleye, yellow perch, northern pike, burbot, common carp, white sucker and shorthead redhorse.
