Côte-Nord-du-Golfe-du-Saint-Laurent is a municipality in the Côte-Nord region of the province of Quebec in Canada. The municipality consists of two non-contiguous areas, both along the shores of the Gulf of Saint Lawrence. The larger main part stretches from the Natashquan River to the Big Mecatina River and includes all populated places. The eastern part is a small section between Middle Bay and Brador.
The Municipality of Côte-Nord-du-Golfe-Saint-Laurent was incorporated in 1963 and originally extended along the shores of the Saint Lawrence from the Natashquan River to the Newfoundland and Labrador provincial border, some 5,240 square kilometres (2,020 sq mi) roughly corresponding to the Basse-Côte-Nord territory. However, with an isolated population scattered over a large area devoid of roads, the municipality did not have an elected municipal council and was managed by an appointed administrator headquartered in Chevery.
