Georgetown is the capital of Ascension Island.

It is also the chief settlement in Ascension Island, in the British Overseas Territory of Saint Helena, Ascension, and Tristan da Cunha, situated on the west coast of the island. The town is centered on St Mary's Church, part of the Anglican Diocese of St Helena, and the former Exiles Club, built as a Royal Marines barracks at the time of Napoleon's exile to Saint Helena in the early 19th century. The town is named after King George III, who reigned at the time the island was claimed for Britain and garrisoned by the Admiralty in 1815. As well as the church, there is a pier, an athletics track, a small supermarket, Royal Mail post office, snack bar, hotel, police station, Georgetown Hospital, dental surgery, and a library. There is no school, however, and pupils travel to Two Boat village, 3 miles inland.
