Argentine Antarctica (Antártida Argentina) is a sector of Antarctica claimed by Argentina as part of its national territory consisting of the Antarctic Peninsula and a triangular section extending to the South Pole. This region overlaps with British and Chilean claims in Antarctica; however, all claims are suspended by the Antarctic Treaty System.
The Argentine exploration of the continent started early in the 20th century. José María Sobral was the first Argentine to set foot on Antarctica in 1902, where he spent 2 seasons with the Swedish Antarctic Expedition of Doctor Otto Nordenskiöld. Shortly afterwards, in 1904, the Orcadas permanent base was already fully operational. Years later other bases would be created, some permanent and others seasonal. The first Argentine expedition to reach the South Pole was the 1965 Operación 90.
Administratively, Argentine Antarctica is a department of the province of Tierra del Fuego, Antarctica, and South Atlantic Islands. The South Orkney Islands are part of Islas del Atlántico Sur (South Atlantic Islands) Department, which include Falkland Islands and South Georgia and South Sandwich Islands (according to Argentine claim).
