Grey Island in the South Orkney Islands is 1 km (0.62 mi) south of Michelsen Island and 2 km (1.2 mi) west of the southern part of Fredriksen Island, in the South Orkney Islands of Antarctica. It was first charted and named Holmen Graa (Grey Island) on a map by the Norwegian whaler Captain Petter Sorlle, who made a running survey of the South Orkney Islands in 1912–13. The anglicised form appears on the chart by Discovery Investigations personnel on the Discovery II who surveyed the islands in 1933.
