The North Fork Flathead River (Ktunaxa: kqaskanmituk ) is a 153-mile (246 km) river flowing through British Columbia, Canada, south into the U.S. state of Montana. It is one of the three primary forks of the Flathead River, the main inflow of Flathead Lake and a tributary of the Columbia River via the Clark Fork River and the Pend Oreille River. The river is sometimes considered the upper headwaters of the Flathead River, although the North Fork is its official name in the U.S. Other naming conventions for the river include Flathead River - North Fork, North Fork of Flathead River, and North Fork of the Flathead River.
