In Argentina, the Day of the Argentine Antarctic, or Argentine Antarctic Sovereignty Day (), is commemorated annually on 22 February. It commemorates what Argentina says was the first permanent settlement, in 1904, in an area later claimed as an integral part of the country. The claimed area is designated a department in the Argentine province of Tierra del Fuego, Antarctica, and the South Atlantic Islands. Argentina has no authority over that part of Antarctica outside its bases. The area is also claimed by the United Kingdom and, in most part, by Chile.
