Trinity Island or Île de la Trinité or Isla Trinidad is an island 24 km (15 mi) long and 10 km (6 mi) wide in the northern part of the Palmer Archipelago, Antarctica. It lies 37 km (23 mi) east of Hoseason Island, 72.6 km (45 mi) south of Deception Island in the South Shetland Islands, and 10.3 km (6 mi) north-northwest of Cape Andreas on the Antarctic Peninsula. The island was named by Otto Nordenskiöld, leader of the 1901-1904 Swedish Antarctic Expedition (SAE) in commemoration of Edward Bransfield's "Trinity Land" of 1820.
