Cosmolabe Rock (Bulgarian: скала Космолабия, romanized: skala Cosmolabe, IPA: [skɐˈla kosmoˈlabija]) is the rock off the NW coast of northwest coast of Nelson Island in the South Shetland Islands, Antarctica extending 120 m in southeast–northwest direction and 50 m wide. Its surface area is 0.23 ha. The vicinity was visited by early 19th century sealers.[1]

The feature is named after the cosmolabe, an instrument created by the French inventor and mathematician Jacques Besson (ca 1540–1573) to be used for navigation, surveying and cartography; in association with other names in the area deriving from the early development or use of geodetic instruments and methods.
