Commonwealth Glacier is a glacier which flows in a southeasterly direction and enters the northern side of Taylor Valley immediately west of Mount Coleman, in Victoria Land, Antarctica. It was charted by the British Antarctic Expedition, 1910–13 (BrAE ), under Robert Falcon Scott, and named by them for the Commonwealth of Australia, which made a financial grant to the BrAE and contributed two members to the Western Geological Party which explored this area.
