The Kerguelen Islands ( or ; in French commonly Îles Kerguelen but officially Archipel Kerguelen, pronounced [kɛʁɡelɛn]), also known as the Desolation Islands (Îles de la Désolation in French), are a group of islands in the sub-Antarctic constituting one of the two exposed parts of the Kerguelen Plateau, a large igneous province mostly submerged in the southern Indian Ocean. They are among the most isolated places on Earth, located more than 3,300 kilometres (1,800 nautical miles) from Madagascar. The islands, along with Adélie Land, the Crozet Islands, Amsterdam and Saint Paul islands, and France's Scattered Islands in the Indian Ocean, are part of the French Southern and Antarctic Lands and are administered as a separate district.

The main island, Grande Terre, is 6,675 km² (2,577 sq mi) in area, about three quarters of the size of Corsica, and is surrounded by a further 300 smaller islands and islets, forming an archipelago of 7,215 km² (2,786 sq mi). The climate is harsh and chilly with frequent high winds throughout the year. The surrounding seas are generally rough and they remain ice-free year-round. There are no indigenous inhabitants, but France maintains a permanent presence of 45 to 100 soldiers, scientists, engineers, and researchers. There are no airports on the islands, so all travel to and from the outside world is conducted by ship.
