Saint Pierre and Miquelon ( MEEK-ə-lon), officially the Territorial Collectivity of Saint Pierre and Miquelon (French: Collectivité territoriale de Saint-Pierre-et-Miquelon), is a self-governing territorial overseas collectivity of France in the northwestern Atlantic Ocean, located near the Canadian province of Newfoundland and Labrador. An archipelago of eight islands, St. Pierre and Miquelon is a vestige of the once-vast territory of New France. Its residents are French citizens. The collectivity elects its own deputy to the National Assembly and participates in senatorial and presidential elections. It covers 242 km² (93 sq mi) of land and had a population of 5,819 as of the January 2022 census. Saint Pierre and Miquelon is an Overseas Country and Territory (OCT) of the European Union, although not an integral part of it. It is neither part of the Schengen area, nor of the European customs territory. On the other hand, Saint Pierre and Miquelon is part of the Eurozone, and its inhabitants have European Union citizenship. The territory is also part of the Regional Joint Cooperation Commission (Atlantic Canada Cooperation) and the Northwest Atlantic Fisheries Organization.

The islands are in the Gulf of St. Lawrence near the entrance of Fortune Bay, which extends into the southwestern coast of Newfoundland, near the Grand Banks of Newfoundland. St. Pierre is 19 kilometres (10+1⁄2 nautical miles) from Point May on the Burin Peninsula of Newfoundland and 3,819 kilometres (2,373 mi) from Brest, the nearest city in Metropolitan France. The tiny Canadian Green Island lies 10 kilometres (5+1⁄2 nmi) east of Saint Pierre, roughly halfway to Point May.
