The highest mountain in the Eastern Alps is Piz Bernina at in the Bernina Group of the Western Rhaetian Alps in Switzerland.

The rocks composing Piz Bernina are diorites and gabbros, while the massif in general is composed of granites (Piz Corvatsch, Piz Palü). Excepting other peaks in the Bernina range, the next highest is the Ortler at in Italian South Tyrol and third the Großglockner at , the highest mountain of Austria. The region around the Großglockner and the adjacent Pasterze Glacier has been a special protection area within the High Tauern National Park since 1986.
