Boatin Island (Bulgarian: остров Боатин, romanized: ostrov Boatin, IPA: [ˈɔstrov boɐˈtin]) is the rocky island off the northwest coast of Robert Island in the South Shetland Islands extending 740 m in north–south direction and 150 m wide. It ends in the T-shaped 250 m wide Hammer Point to the north, and connected to Robert Island to the south by a 250 m long moraine tombolo. The feature was formed as a result of the retreat of Robert Island's ice cap during the first decade of 21st century. The area was visited by early 19th century sealers.
