Koms Glacier () is a glacier, 5 nautical miles (9 km) long, flowing north between Mefjell Mountain and Komsa Mountain in the Sør Rondane Mountains. It was mapped by Norwegian cartographers in 1957 from air photos taken by U.S. Navy Operation Highjump, 1946–47, and named Komsbreen (the Lapp cradle glacier).
