Saint Martin (French: Saint-Martin), officially the Collectivity of Saint Martin (Collectivité de Saint-Martin) is an overseas collectivity of France in the Caribbean. With a population of 36,286 (as of Jan. 2011) on an area of 53.2 square kilometres (20.5 sq mi), it encompasses the northern 60% of the divided island of Saint Martin, and some neighbouring islets, the largest of which is Île Tintamarre. The southern 40% of the island of Saint Martin constitute Sint Maarten, since 2010 a constituent country of the Kingdom of the Netherlands.

Before 2007, the French part of Saint Martin formed a part of the French overseas région and département of Guadeloupe. Saint Martin is separated from the island of Anguilla by the Anguilla Channel. Its capital is Marigot.

Saint Martin was for many years a French commune, forming part of Guadeloupe, which is an overseas région and département of France. In 2003 the population of the French part of the island voted in favour of secession from Guadeloupe in order to form a separate overseas collectivity (COM) of France. On 9 February 2007, the French Parliament passed a bill granting COM status to both the French part of Saint Martin and (separately) the neighbouring Saint Barthélemy. The new status took effect on 15 July 2007, once the local assemblies were elected, with the second leg of the vote ultimately occurring on 15 July 2007. Saint Martin remains part of the European Union.
