Cave Island (62°26′55″S 60°3′40″W / 62.44861°S 60.06111°WCoordinates: 62°26′55″S 60°3′40″W / 62.44861°S 60.06111°W) is an island marked by a large cavern in its south side, which is the second largest of the Meade Islands lying in the north entrance to McFarlane Strait, off Archar Peninsula on Greenwich Island in the South Shetland Islands. It is separated from neighbouring Zverino Island to the west-southwest by the 110 m wide Glogovo Passage.
The name Cave Rock appears to have been applied by DI personnel on the Discovery II who charted the feature in 1935.
