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.

The glacier is heavily crevassed in its lower half, receiving ice influx also from Balkan Snowfield and from the part of the island’s ice cap that is located west of Hemus Peak and Gurev Gap and south of Saedinenie Snowfield, and is draining southwards. It exhibits pyroclastic phenomena typical of the region’s glaciology and resulting from volcanic activities at Deception Island not 40 km away.

The glacier was mapped by the Spanish Servicio Geográfico del Ejército in 1991, the lower portion in greater detail. Bulgarian remapping of Perunika Glacier’s terminus from a survey made during the summer of 1995-96; mapping in 2005 and 2009 from the Bulgarian topographic survey Tangra 2004/05.

Perunika is the name of a village in the Rhodope Mountains in southern Bulgaria. A derivation of Perun, the name of ancient Slavic God.

The glacier is centred at 62°36′45″S 60°15′48″W / 62.61250°S 60.26333°W / -62.61250; -60.26333.
