Sprey Island (Bulgarian: остров Спрей, romanized: ostrov Sprey, IPA: [ˈɔstrof ˈsprɛj]) is the mostly ice-covered island 1.23 km long in southwest–northeast direction and 460 m wide in the Dannebrog Islands group of Wilhelm Archipelago in the Antarctic Peninsula region.

Its surface area is 27.94 ha.

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