The Duroch Islands are a group of islands and rocks which extend over an area of about 5 km² (1.9 sq mi), centred about 1 km (0.62 mi) off Cape Legoupil on the north coast of Trinity Peninsula, Antarctica. They were discovered by a French expedition under Captain Jules Dumont d'Urville, 1837–40, who gave the name "Rocher Duroch" to one of the larger islands in the group after Ensign Joseph Duroch of d'Urville's expedition ship, the Astrolabe. The Falkland Islands Dependencies Survey, which charted the islands in 1946, recommended that the name Duroch be extended to include the entire group of islands.
