Cairns Glacier (78°34′S 86°00′W / 78.567°S 86.000°W / -78.567; -86.000) is a glacier on the west slope of Vinson Massif, Sentinel Range in Antarctica, situated between Branscomb Glacier and Tulaczyk Glacier. It flows along the northwest side of Brichebor Peak southwestwards, and leaving the range together with Tulaczyk Glacier joins Nimitz Glacier southeast of Klenova Peak.

The feature was named by US-ACAN (2006) after Stephen Douglas Cairns, research zoologist, Department of Invertebrate Zoology, National Museum of Natural History, Smithsonian Institution, 1985–2006; Board of Associated Editors, Antarctic Research Series, American Geophysical Union, 1990–95.
