Anchialus Glacier (Bulgarian: ледник Анхиало, romanized: lednik Anchialo, IPA: [ˈlɛdnik anxiˈaɫo]) is the 8.5 km long and 3.4 km wide glacier in Sostra Heights on the east side of northern Sentinel Range in Ellsworth Mountains, Antarctica.

The glacier drains the northeast slopes of Mount Malone and the west slopes of Bracken Peak, flows northwards and joins Newcomer Glacier east of Mount Lanning.

The glacier is named after the ancient town of Anchialus in Southeastern Bulgaria.
