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.

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.

[2] The feature is named after Juturna, a Roman deity of springs and streams, daughter of Volturnus.
