Tatul Island (Bulgarian: остров Татул, romanized: ostrov Tatul, IPA: [ˈɔstrof tɐˈtuɫ]) is a triangular ice-free island off the north coast of Robert Island in the South Shetland Islands, Antarctica.

Extending 350 by 200 m (380 by 220 yd), the island emerged as a distinct geographical entity following the retreat of Robert Island's ice cap in the late 20th and early 21st century.

The feature is named after the settlement of Tatul adjacent to a major Thracian shrine complex in the Rhodope Mountains, Bulgaria related to the cult of Orpheus.
