The Antarctic fur seal (Arctocephalus gazella) is one of eight seals in the genus Arctocephalus, and one of nine fur seals in the subfamily Arctocephalinae. As its name suggests, the Antarctic fur seal is distributed in Antarctic waters. Around 95% of the world population breeds at the Island of South Georgia. It is named for the German naval vessel, the corvette SMS Gazelle, which collected the first specimen from Kerguelen Island. The species is also known as the Kerguelen fur seal.

This fur seal has a short and broad snout compared with others in the family. Adult males are dark brown in colour. Females and juveniles tend to be grey with a lighter undersides. Colour patterns are highly variable, and some scientists believe some hybridisation with subantarctic fur seals has occurred. Pups are dark brown, nearly black at birth. About one in 1000 Antarctic fur seals are pale 'blonde' variants.

Males are substantially bigger than females. Antarctic fur seals grow 2 m (6.5 ft) long and weigh 91 kg (200 lb) to 209 kg (460 lb). Males live for about 15 years and females up to 25.

The Antarctic ( /ænˈtɑrktɪk/ or  /ænˈtɑrtɪk/) is a polar region, specifically the region around the Earth's South Pole, opposite the Arctic region around the North Pole. The Antarctic comprises the continent of Antarctica and the ice shelves, waters, and island territories in the Southern Ocean situated south of the Antarctic Convergence. The region covers some 20% of the Southern Hemisphere, of which 5.5% (14 million km²) is the surface area of the continent itself.

The maritime part of the region constitutes the area of application of the international Convention for the Conservation of Antarctic Marine Living Resources (CCAMLR), where for technical reasons the Convention uses an approximation of the Convergence line by means of a line joining specified points along parallels of latitude and meridians of longitude. The implementation of the Convention is managed through an international Commission headquartered in Hobart, Australia by an efficient system of annual fishing quotas, licenses and international inspectors on the fishing vessels, as well as satellite surveillance.
