The coat of arms of the British Antarctic Territory was first granted in 1952, when the territory was still a dependency of the Falkland Islands (along with South Georgia and the South Sandwich Islands).^[1]

The arms consist of a shield bearing a flaming torch on a wavy background representing the sea. The dexter supporter is a golden lion, representing the United Kingdom.^[2] The sinister supporter is an Emperor penguin, representing the native wildlife in the territory.^[2] The lion stands on a compartment of grass, while the penguin stands on a compartment of ice.^[1] The crest is a representation of the RRS Discovery, the research ship used in 1901 by the caption Robert Falcon Scott on his first journey to the Antarctic.^[3]

The coat of arms appears in the fly of the flag of the British Antarctic Territory.^[2][3]

The official blazon granted by the British College of Arms is as follows:^[4]
