Sirma Glacier (Bulgarian: ледник Сирма, romanized: lednik Sirma, IPA: [ˈlɛdnik ˈsirmɐ]) is the 4 nautical miles (7.4 km; 4.6 mi) long and 2 nautical miles (3.7 km; 2.3 mi) wide glacier on the west side of Owen Ridge in southern Sentinel Range, Ellsworth Mountains in Antarctica, situated south of Bolgrad Glacier, and flowing west-southwestwards from Mount Southwick, Mount Milton and Mount Inderbitzen to leave the range and join Nimitz Glacier northwest of Modren Peak.
The glacier is named after the Bulgarian woman rebel leader Sirma Voyvoda (1773-1858).
