The British Antarctic Territory (BAT) is a sector of Antarctica claimed by the United Kingdom as one of its 14 British Overseas Territories. It comprises the region south of 60°S latitude and between longitudes 20°W and 80°W, forming a wedge shape that extends to the South Pole. The Territory was formed on 3 March 1962, although the UK's claim to this portion of the Antarctic dates back to Letters Patent of 1908 and 1917. The area now covered by the Territory includes three regions which, before 1962, were administered by the British as separate dependencies of the Falkland Islands: Graham Land, the South Orkney Islands, and the South Shetland Islands. The Territory overlaps the Antarctic claims of Argentina (Argentine Antarctica) and Chile (Antártica Chilena Province) is not been recognized by the United Nations, U.S., Russia or by most other countries (other than Australia and New Zealand). It is inhabited by the staff of research and support stations operated and maintained by the British Antarctic Survey and other organisations, and stations of Argentina, Chile and other countries. There are no native inhabitants. Capital: Rothera (Main base). Chief Stations: Halley V, Rothera, Signy.

The British Antarctic Survey has two permanently staffed research stations in the Territory: Halley and Rothera.
Signy was operated from 1947 until 1996 and now is only staffed in the summer. There are also two summer-only forward operating stations, at Fossil Bluff and Sky Blu. Faraday was maintained until 1996, when it was sold to Ukraine and renamed Akademik Vernadsky Station. Since 1996, the historic base at Port Lockroy on Goudier Island has been staffed by the UK Antarctic Heritage Trust during the Antarctic summer. Receiving about 10,000 visitors a year, it is one of the most visited sites on the continent. Visitors can tour the museum, buy souvenirs, post mail, and view the large gentoo penguin colony. Argentine presence in the territory dates to the foundation of the Orcadas Base, South Orkney Islands, in 1903. A number of other nations maintain bases in the territory, many in the South Shetland Islands.

Territorial Disputes: Mauritius claims the Chagos Archipelago including Diego Garcia; in 2001, the former inhabitants of the Chagos Archipelago, evicted in 1967 and 1973 and now residing chiefly in Mauritius, were granted UK citizenship and the right to repatriation; in May 2007, the UK Court of Appeals upheld the May 2006 High Court of London judgment reversing the UK government's 2004 Orders of Council that banned habitation on the islands, but the ban was upheld 22 Oct 2008 by the British House of Lords; a small group of Chagossians visited Diego Garcia in Apr 2006; repatriation is complicated by the exclusive US military lease of Diego Garcia that restricts access to the largest viable island in the chain, the US lease on Diego Garcia expires in 2016.
 
Currency: Despite the lack of permanent inhabitants, the British Antarctic Territory issues its own postage stamps. While some are actually used by visiting tourists and resident scientists, the bulk are sold overseas to collectors. The first issue came in 1963, an engraved set with 15 values ranging from ˝d to one pound, featuring a portrait of Queen Elizabeth overlooking various scenes of human activity in Antarctica. Several additional issues in the 1960s were followed by a decimalisation issue in 1971 produced by overprinting the 1963 stamps. Although nominally British, the British Antarctic Territory is subject to international agreements which limit British authority there and allow other countries to maintain scientific research bases there. The official currency is the Pound sterling. Legal notices have appeared in the London Gazette in relation to the currency of the British Antarctic Territory, for example when the farthing, halfpenny, and half crown were demonetised in the late 1960s and early 1970s. The dates for demonetisation did not correspond to the equivalent dates in the United Kingdom, and were often about a year behind. The official currency in these territories is either sterling or a local currency that evolved from sterling and is at a fixed one-to-one parity with sterling. In 2008/2009, as part of the celebrations of the centenary of the 1908 British territorial claim and 1959 Antarctic Treaty, the British Antarctic Territory issued its first ever legal-tender coins.
