Kril Island (Bulgarian: остров Крил, romanized: ostrov Kril, IPA: [ˈɔstrof ˈkriɫ]) is the mostly ice-covered island 1.2 km long in southwest–northeast direction and 310 m wide in the Wauwermans Islands group of Wilhelm Archipelago in the Antarctic Peninsula region.

Its surface area is 24.92 ha.

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

[1] Kril Island is located 4.15 km south-southeast of Host Island, 275 m northwest of Lobel Island, 6.62 km north-northwest of False Cape Renard on Graham Land, and 5.55 km northeast of Mishka Island in the Dannebrog Islands group.
