The Collectivity of Saint Martin (Collectivité de Saint-Martin), commonly known as simply Saint Martin (Saint-Martin), is an overseas collectivity of France in the West Indies in the Caribbean. With a population of 36,286 (as of January 2011) on an area of 53.2 km2, 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 constitutes Sint Maarten, since 2010 a constituent country of the Kingdom of the Netherlands. This marks the only place in the world that France borders 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.
Hurricane Irma hit the island on 6–7 September 2017 with Category 5 winds causing widespread and significant damage to buildings and infrastructure. As of 10 September, reports indicated that ten deaths were attributed to the storm on this island and on Saint Barthelemy (combined) and that seven people were still missing.
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.
The new governance structure befitting an overseas collectivity took effect on 15 July 2007 with the first session of the Territorial Council (Conseil territorial) and the election of Louis-Constant Fleming as president of the Territorial Council. On 25 July 2008 Fleming resigned after being sanctioned by the Conseil d'État for one year over problems with his 2007 election campaign. On 7 August, Frantz Gumbs was elected as President of the Territorial Council. However, his election was declared invalid on 10 April 2009 and Daniel Gibbs appointed as Acting President of the Territorial Council on 14 April 2009. Gumbs was reelected on 5 May 2009.
Before 2007, Saint Martin was coded as GP (Guadeloupe) in ISO 3166-1. In October 2007, it received the ISO 3166-1 code MF (alpha-2 code), MAF (alpha-3 code), and 663 (numeric code).
