Yastreb Island (Bulgarian: остров Ястреб, romanized: ostrov Yastreb, IPA: [ˈɔstrof ˈjastrɛp]) is the mostly ice-covered island 934 m long in west-southwest to east-northeast direction and 317 m wide in the Dannebrog Islands group of Wilhelm Archipelago in the Antarctic Peninsula region.

Its surface area is 17.12 ha.

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