Sugarloaf Island is a conspicuous small island which lies close to the east side of Clarence Island, midway between Cape Lloyd and Cape Bowles, in the South Shetland Islands, Antarctica. It lies 3.2 km north of Lebed Point, on the northern side of the entrance to Istros Bay. The name was in use by American and British sealers as early as 1822 and is now well established.

Important Bird Area

An 82 ha site, comprising all of Sugarloaf Island, the neighbouring ice-free coastal area of Clarence Island and the intervening marine area, has been designated an Important Bird Area (IBA) by BirdLife International because it supports a total of about 70,000 pairs of chinstrap penguins, as well as some 25,000 pairs of southern fulmars on the adjacent ice-free slopes of Clarence Island.^[1]
