Balanstra Glacier (Bulgarian: ледник Баланстра, romanized: lednik Balanstra, IPA: [ˈlɛdniɡ bɐˈɫanstrɐ]) is the 12 km long and 4 km wide glacier on Brabant Island in the Palmer Archipelago, Antarctica situated northeast of Hippocrates Glacier and southwest of Mackenzie Glacier. It drains the southeast slopes of Stribog Mountains, flows east-southeastwards and enters Pampa Passage south of Momino Point and north of Pinel Point.
The glacier is named after the ancient Roman station of Balanstra in Western Bulgaria.
