Kosatka Island (Bulgarian: остров Косатка, romanized: ostrov Kosatka, IPA: [ˈɔstrof koˈsatkɐ]) is the mostly ice-covered island 653 m long in west–east direction and 195 m wide in the Dannebrog Islands group of Wilhelm Archipelago in the Antarctic Peninsula region. Its surface area is 8.86 ha.
The feature is so named because of its shape supposedly resembling a killer whale ('kosatka' in Bulgarian), and in association with other descriptive names of islands in the area.
