Groma Rock (Bulgarian: скала Грома, romanized: skala Groma, IPA: [skɐˈla ˈgrɔmɐ]) is the 45 m long in south-north direction and 30 m wide rock off the northwest extremity of Low Island in the South Shetland Islands. Its surface area is 0.1 ha.

The feature is named after the ancient Roman surveying instrument groma, and in association with other names in the area deriving from the early development or use of geodetic instruments and methods.
