Schefferville is a town in the Canadian province of Quebec. Schefferville is in the heart of the Naskapi and Innu territory in northern Quebec, less than 2 km from the border with Labrador on the north shore of Knob Lake. It is located within the Caniapiscau Regional County Municipality and has an area of 24.76 square kilometres (9.56 sq mi). Schefferville completely surrounds the autonomous Innu community of Matimekosh, and it abuts the small community of Lac-John Reserve. Both of the latter communities are First Nations Innu reserves. Schefferville is also close to the Naskapi reserved land of Kawawachikamach.

The Naskapi are an Indigenous people of the Subarctic native to the historical country St'aschinuw, which is located in northern Quebec and Labrador, neighbouring Nunavik. They are closely related to Innu Nation, who call their homeland Nitassinan.
