Argentine Antarctica
Argentina's territorial claim in Antarctica
Argentine Antarctica (Spanish: Antártida Argentina or Sector Antártico Argentino) is an area on Antarctica claimed by Argentina as part of its national territory. It consists of the Antarctic Peninsula and a triangular section extending to the South Pole, delimited by the 25° West and 74° West meridians and the 60° South parallel. This region overlaps with British and Chilean claims in Antarctica.
Argentina's Antarctic claim is based on its presence on a base on Laurie Island in the South Orkney Islands since 1904, along with the area's proximity to the South American continent, and is subject to the Antarctic Treaty; however, the presence on the Antarctic mainland was established in 1951, and the official claim on the mainland was started to be formulated on 1941, with several changes and was officially declared on 1957. Administratively, Argentine Antarctica is a department of the province of Tierra del Fuego, Antarctica, and South Atlantic Islands. The provincial authorities are based in Ushuaia. Argentine activities in Antarctica are coordinated by the Instituto Antártico Argentino (IAA) and Argentine Antarctic Program.
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 two seasons with the Swedish Antarctic Expedition of Otto Nordenskiöld. Shortly afterward, in 1904, the Orcadas Permanent Base was established.

Why this record matters
“Argentine Antarctica” is worth following because a concise public description often conceals a longer documentary argument. Here, Argentine, Antarctica and Argentina's provides the most credible route into that argument.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 17, 2026. The linked authority identifier is Q646243. Authority coordinates are -75.000, -49.500. 3 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1904, 1951, 1941 and 1957.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
