The France–Netherlands border, or Saint Martin–Sint Maarten border, is the border between the 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.
