Perunika Glacier (Bulgarian: ледник Перуника, romanized: lednik Perunika, IPA: [ˈlɛdnik pɛroˈnikɐ]) is an 8 km long and 3 km wide (average) roughly crescent-shaped glacier in eastern Livingston Island in the South Shetland Islands, Antarctica situated east of Pimpirev Glacier, south of Saedinenie Snowfield, southwest of Kaliakra Glacier, west of Huron Glacier, and north of Balkan Snowfield and the head of Huntress Glacier.
Its head is bounded by Pliska Ridge to the south-southwest, Nesebar Gap to the south, Wörner Gap to the east, and Bowles Ridge to the north-northeast. It drains northwestwards between Burdick Ridge and Bowles Ridge, then north of Rezen Knoll turns west-southwest and flows into the head of Emona Anchorage between Bulgarian Beach and Pimpirev Beach.
