Quick Answer: SXM Island refers to the Dutch Caribbean island of Sint Maarten, which shares the island of Saint Martin with the French Republic. The island is located in the northeastern Caribbean Sea, approximately 300 miles (480 km) east of Puerto Rico. The island is divided roughly 60% to the Netherlands (Sint Maarten) and 40% to France (Saint-Martin).

Key Facts

Overview

SXM Island is commonly used as shorthand for the island of Saint Martin, which is shared between two nations: the Kingdom of the Netherlands and France. The island is located in the northeastern Caribbean, part of the Leeward Islands chain, and is a popular destination for tourists due to its beaches, duty-free shopping, and vibrant culture.

The northern part of the island is the French overseas collectivity of Saint-Martin, while the southern portion is the country of Sint Maarten, an autonomous nation within the Kingdom of the Netherlands. Despite its small size, the island has two distinct legal systems, currencies, and administrative structures.

How It Works

The dual governance of SXM Island is rooted in a 1648 treaty between the Dutch Republic and France, making it one of the oldest continuously observed international borders in the Western Hemisphere. This unique arrangement allows for open borders and free movement between the two sides.
