Peperuda Island (Bulgarian: остров Пеперуда, romanized: ostrov Peperuda, IPA: [ˈɔstrof pɛpɛˈrudɐ]) is the mostly ice-free island 592 m long in west-southwest to east-northeast direction and 309 m wide in the Wilhelm Archipelago, Antarctic Peninsula region. Its surface area is 9.51 ha.

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