Klebelsberg Glacier () is a glacier, 7 nautical miles (13 km) long and 2 nautical miles (3.7 km) wide, situated at the south side of Finsterwalder Glacier and flowing northwest from the central plateau of Graham Land toward the head of Lallemand Fjord. With Finsterwalder and Haefeli Glaciers, its mouth merges with Sharp Glacier where the latter enters the fjord. First surveyed from the plateau in 1946-47 by the Falkland Islands Dependencies Survey (FIDS), and named by them for Raimund von Klebelsberg, Austrian glaciologist.
