Pyramid Island is a conspicuous, pillar-shaped rocky island rising to 205 m off the north entrance to McFarlane Strait in the South Shetland Islands, Antarctica. Its surface area is 9 ha. Cone Rock (-62.43247°N, -60.10231°W) is rising to 6 m 1.33 km south of the island, 2.03 km north-northwest of Meade Islands, 2.8 km northeast of Williams Point and 1.65 km east of Koshava Island, Zed Islands. The vicinity of Pyramid Island was visited on 19 February 1819 during the discovery of the South Shetlands by Captain William Smith in the British brig Williams, and later by early 19th century sealers. Both the island and the rock were charted and descriptively named by Discovery Investigations personnel in 1935.
