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 25.11 square kilometres (9.70 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 isolated town is not connected to the provincial road network but is accessible by airplane via the Schefferville Airport or by train. Schefferville is the northern terminus of Tshiuetin Rail Transportation (formerly operated by the Quebec North Shore and Labrador Railway) with service to Sept-Îles.
McGill University operates the McGill Subarctic Research Station in Schefferville.
