The Grossglockner (German: Großglockner or just Glockner) is, at 3,798 meters above the Adriatic (12,461 ft), the highest mountain of Austria and the highest mountain in the Alps east of the Brenner Pass. It is part of the larger Glockner Group of the Hohe Tauern range, situated along the main ridge of the Central Eastern Alps and the Alpine divide. The Pasterze, Austria's most extended glacier, lies on the Grossglockner's eastern slope.

The characteristically pyramid-shaped peak actually consists of two pinnacles, the Grossglockner and the Kleinglockner (3,770 m (12,370 ft), from German: klein, "small"), separated by a saddle-like formation known as the Glocknerscharte.
