Saint Barthélemy, officially the Collectivité territoriale de Saint-Barthélemy, also known as St. Barts (English) or St. Barth (French), is an overseas collectivity of France in the Caribbean. The island lies about 30 kilometres (19 mi) southeast of the island of Saint Martin; it is northeast of the Dutch islands of Saba and Sint Eustatius, as well as north of the independent country of Saint Kitts and Nevis.

French is a Romance language of the Indo-European family. It descended from the Vulgar Latin of the Roman Empire, as did all Romance languages. French evolved from Gallo-Romance, the Latin spoken in Gaul, and more specifically in Northern Gaul. Its closest relatives are the other langues d'oïl—languages historically spoken in northern France and in southern Belgium, which French (Francien) largely supplanted. French was also influenced by native Celtic languages of Northern Roman Gaul like Gallia Belgica and by the (Germanic) Frankish language of the post-Roman Frankish invaders. Today, owing to the French colonial empire, there are numerous French-based creole languages, most notably Haitian Creole. A French-speaking person or nation may be referred to as Francophone in both English and French.
