Corsica is an island in the Mediterranean Sea belonging to France. It is located west of the Italian Peninsula, southeast of the French mainland, and north of the Italian island of Sardinia. Mountains make up two-thirds of the island, forming a single chain.

Corsica is one of the 18 regions of France, though it is also designated as a territorial collectivity (collectivité territoriale) by law. As a territorial collectivity, Corsica enjoys a greater degree of autonomy than other French regions; for example, the Corsican Assembly is able to exercise limited executive powers.

The island formed a single department until it was split in 1975 into two departments: Haute-Corse (Upper Corsica) and Corse-du-Sud (Southern Corsica), with its regional capital in Ajaccio, the prefecture city of Corse-du-Sud. Bastia, the prefecture city of Haute-Corse, is the second-largest settlement in Corsica.
