The Gaspé Peninsula or just the Gaspé is a North American peninsula on the south shore of the Saint Lawrence River, in Quebec, Canada. It extends into the Gulf of Saint Lawrence and is bounded on the south by New Brunswick, from which it is partially divided by the Baie des Chaleurs.

Together with the Magdalen Islands, the Gaspé makes up the Quebec region of Gaspésie-Îles-de-la-Madeleine.

There is a town in the peninsula that is also called Gaspé; see Gaspé, Quebec.
