Saint Martin–Sint Maarten border
International border
The Saint Martin–Sint Maarten border, or France–Netherlands border, is the border between the Collectivity of Saint Martin, an overseas collectivity of France, and Sint Maarten, a constituent country of the Kingdom of the Netherlands, on the island of Saint Martin in the Caribbean. The 87-square-kilometre (34 sq mi) island is divided roughly 60:40 between the French Republic (53 km2, 20 sq mi)[1] and the Kingdom of the Netherlands (34 km2, 13 sq mi)[2] by the 16 km (10 mi) border.[3] However, the two parts are roughly equal in population.
The border is completely open and can be crossed freely.[4]
