The Grossglockner (German: Großglockner, Slovene: Veliki Klek) is, at 3,798 m above sea level, Austria’s highest mountain and the highest mountain in the Alps east of the Brenner Pass. This makes it, after Mont Blanc, the second most prominent mountain in the Alps, when measured by relative height; see the list of Alpine peaks by prominence.

The Grossglockner lies on the border between Carinthia and the East Tyrol; it is the highest peak in the Glockner group, a group of mountains along the main ridge of the Hohe Tauern. The summit itself lies on the Glockner ridge, which branches to the south off the main ridge. The Pasterze, Austria’s biggest glacier, lies at the Grossglockner’s foot.

The characteristically pyramid-shaped peak actually consists of two pinnacles, the Grossglockner and the Kleinglockner (3,770 m; klein means „small“ in German), separated by a saddle-like formation known as the Glocknerscharte.
