Juturna Lake (Bulgarian: езеро Ютурна, romanized: ezero Yuturna, IPA: [ˈɛzɛro juˈturnɐ]) is the roughly triangular lake extending 220 m in west-east direction and 150 m in north-south direction at the east extremity of South Beaches on Byers Peninsula, Livingston Island in the South Shetland Islands, Antarctica. Its surface area is 1.9 ha. The lake is separated from sea by a 40 to 57 m wide strip of land, and drains by way of a 260 m long stream flowing into the sea west of Rish Point. It is surmounted by Ritli Hill on the east. The area was visited by early 19th century sealers.
