Shut Island (Bulgarian: остров Шут, romanized: ostrov Shut, IPA: [ˈɔstrof ˈʃut]) is the partly ice-free island extending 573 m in west–east direction and 520 m in south–north direction in the Dannebrog Islands group of Wilhelm Archipelago in the Antarctic Peninsula region. Its surface area is 14 ha.

The feature is so named because of its shape supposedly resembling a jester hat ('shut' being the Bulgarian for 'jester'), and in association with other descriptive names of islands in the area.

Shut Island is located at 65°03′00″S 64°10′00″W / 65.05000°S 64.16667°W / -65.05000; -64.16667. It abuts Padpadak Island on the south, and is situated 815m south-southwest of Hoatsin Island, 3.92 km west of Revolver Island and 1.9 km northeast of Skoba Island.
