The Île de Sein is a Breton island in the Atlantic Ocean, off Finistère, eight kilometres from the Pointe du Raz, from which it is separated by the Raz de Sein. Its Breton name is Enez-Sun. The island, with its neighbouring islets, forms the commune of Île-de-Sein in the Finistère department of Brittany in north-western France. Inhabitants of Île-de-Sein are called in French Sénans.
