Turtle Mountain Indian Reservation is a reservation located in northern North Dakota, United States. It is the land base for the Turtle Mountain Band of Chippewa Indians. The population of the Turtle Mountain Indian Reservation consists of Plains Ojibwe and Métis peoples; the reservation was established in 1882.

The Métis are an Indigenous people whose historical homelands include Canada's three Prairie Provinces, as well as parts of British Columbia, the Northwest Territories, Northwest Ontario and the northern United States. They have a shared history and culture, deriving from specific mixed European and Indigenous ancestry, which became distinct through ethnogenesis by the mid-18th century, during the early years of the North American fur trade.
