The Chiloé Archipelago consists of several islands lying off the coast of Chile. It is separated from mainland Chile by Chacao Channel in the north, the Sea of Chiloé in the east and Gulf of Corcovado to the southeast. All of the archipelago—except Desertores Islands, which are part of Palena Province—forms the province of Chiloé. The main island is Chiloé Island (Isla Grande de Chiloé).
