Clarence Island is an uninhabited island in the South Shetland Islands archipelago off the northwestern edge of the Antarctic Peninsula. It is part of the remote, largely ice-covered island groups that surround the peninsula and is subject to Antarctic environmental conditions.

The island is rugged and glaciated with no permanent human settlement; it is visited only occasionally by scientific or expedition vessels operating in the South Shetlands. Wildlife typical of the region may occur nearby, but there are no facilities or infrastructure on the island.

Geographically the island sits among the South Shetland chain in the Southern Ocean, far from any continental settlement and accessible only by ship during the austral summer window when sea and ice conditions permit passage.
