Devil's Island (French: īle du Diable) is the third largest island of the Īles du Salut island group in the Atlantic Ocean. It is located approximately 14 km (9 mi) off the coast of French Guiana in South America just north of the town of Kourou. It has an area of 14 ha (34.6 acres). The island was a part of the notorious French penal colony of French Guiana for 101 years, from 1852 to 1953. The island was used primarily to house political prisoners.
English speakers have come to use the island's name to refer to the entire former prison system of French Guyana; however, French speakers refer to it as the Bagne de Cayenne (Cayennes penal colony)
