Grande-Vallée (French pronunciation: [ɡʁɑ̃d vale]) is a municipality in the Gaspésie-Îles-de-la-Madeleine region of the province of Quebec in Canada.

In 1691, Governor General Frontenac granted the area to François Hazeur, a prosperous merchant from Quebec City.

It was inherited by Hazeur's son-in-law, Michel Sarrazin, a surgeon, biologist, and doctor of the King.

In 1842, Alexis Caron and his family, also from Saint-Thomas-de-Montmagny, became the first permanent settlers.

[1][4] On September 15, 1927, the village was incorporated as a parish municipality, with Arthur S. Fournier as first mayor, although its status as parish municipality was not officially recognized until 1995.
