Abrupt Island, also known as Brattöy, is a small, uninhabited island in Antarctica. It is about 0.8 kilometers (0.5 miles) wide and lies roughly 2.4 kilometers (1.5 miles) east of Lang Island, in the Øygarden Group near Edward VIII Bay. Norwegian cartographers first mapped it from aerial photos taken during the Lars Christensen Expedition in 1936–37, naming it Brattoy, meaning "abrupt island." The name was later translated by ANCA after an Australian National Antarctic Research Expeditions survey in 1954. The island is administered under the Antarctic Treaty System.
