Lac-John (French pronunciation: [lak dʒɔn]) is a First Nations reserve on John Lake in the Côte-Nord region of Quebec, Canada, about 3.5 kilometres (2.2 mi) north-east from the centre of Schefferville.

[4] The region was the northern limit of the hunting and trapping grounds of the Innu indigenous people, but they never had resided there permanently.

Because of mining development in the early 1950s, the Naskapi from Fort Chimo and a dozen Innu families from Maliotenam arrived at Schefferville to serve as guides for geological exploration work, and help on the railway construction from Sept-Iles.

[4][5] In 1957, the Schefferville municipal authorities moved the Innu and Naskapi to a site on John Lake, where they lived in poverty without sanitation, electricity, schools, or a medical facility.

The Innu and Naskapi initially lived in tiny shacks, but by 1962 Indian and Northern Affairs had built 30 houses for them.
