Dint Island is a rocky island, 1.50NaN0 long. Probably first seen from the air by the United States Antarctic Service, 1939–41, it was first mapped from air photos taken by the Ronne Antarctic Research Expedition, 1947–48, by D. Searle of the Falkland Islands Dependencies Survey in 1960. It was so named by the UK Antarctic Place-Names Committee because a distinctive cirque makes a dent, or dint, on the south side of the island.
Dint Island is located at and lies 20NaN0 off the west side of Alexander Island within Lazarev Bay. The island lies roughly 6 miles (10 km) southeast of Umber Island.
