Sint Maarten is a constituent country of the Kingdom of the Netherlands in the Caribbean. With a population of 41,486 as of January 2019 on an area of 34 km2 (13 sq mi), it encompasses the southern 44% of the divided island of Saint Martin, while the northern 56% of the island constitutes the French overseas collectivity of Saint Martin.

It is commonly believed that Christopher Columbus named the island in honor of Saint Martin of Tours when he encountered it on his second voyage of discovery. However, he actually applied the name to the island now called Nevis when he anchored offshore on November 11, 1493, the feast day of Saint Martin. The confusion of numerous poorly charted small islands in the Leeward Islands meant that this name was accidentally transferred to the island now known as Saint-Martin/Sint Maarten.
