Cockburn Island is an oval island 2.7 kilometres (1.7 mi) long, consisting of a high plateau with steep slopes surmounted on the northwest side by a pyramidal peak 450 m (1,476 ft) high, lying in the north-east entrance to Admiralty Sound, south of the north-east end of Antarctic Peninsula. It was discovered by a British expedition under Ross, 1839-43, who named it for Admiral George Cockburn, Royal Navy, then senior Lord of the Admiralty.
The island has been identified as an Important Bird Area (IBA) by BirdLife International because it supports a breeding colony of about 800 pairs of Imperial Shags. Although a large colony of Adélie Penguins and Snow Petrel nests were reported from the island in 1901, it is not known whether they continue to breed there.
