Indigenous peoples of the Northwest Plateau


Indigenous peoples of the Northwest Plateau, also referred to by the phrase Indigenous peoples of the Plateau, and historically called the Plateau Indians (though comprising many groups) are indigenous peoples of the Interior of British Columbia, Canada, and the non-coastal regions of the United States Pacific Northwest states.

Their territories are located in the inland portions of the basins of the Columbia and Fraser Rivers. These tribes live in parts of the Central and Southern Interior of British Columbia, northern Idaho, western Montana, eastern Washington, eastern Oregon, and northeastern California. The eastern flank of the Cascade Range lies within the territory of the Plateau peoples.

In Canada, the greater part of the Interior Plateau was inhabited by Interior Salish peoples: the Lillooet tribe whose homelands are in the Lillooet River Valley; the Thompson First Nations, whose homelands are in the Fraser River Valley from Yale to Lillooet; the Secwepemc (Shuswap) of the Fraser River Valley from Lillooet to Alexandria, the upper parts of the Thompson River basin, and areas further east; the Okanagan of the Okanagan River Valley and its vicinity; also the Lakes people of the Arrow Lakes. The Kutenai tribe, who live in the southeastern parts of British Columbia and formerly extended to southwestern Alberta, speak an isolate language. Athapaskan-speaking people, the Chilcotin and Carrier, occupy the northernmost part of the Plateau region.
