The Dunantspitze, formerly called Ostspitze, is a peak of the Monte Rosa Massif in the Pennine Alps in Switzerland. It is the second highest peak of the massif, after the Dufourspitze (4,634 m) and the second highest summit in Switzerland, but its prominence is only about 15 metres. At the time of its first ascent it was unclear which of the summits was the higher.

Monte Rosa is a mountain massif in the eastern part of the Pennine Alps, on the border between Italy and Switzerland (Valais). The highest peak of the massif, amongst several peaks of over 4.000 m, is the Dufourspitze, the second highest mountain in the Alps and western Europe, after Mont Blanc. The east face of the Monte Rosa towards Italy has a height of about 2.400 meters and is the highest mountain wall of the Alps.

The nearly vertical eastern wall (behind, not visible) has a height greater than the visible part in front.
The eastern wall of the Monte Rosa is on Italian territory. The Macugnaga wall has a height of ca. 2400 m above the Valley of Anzasca below and is the highest mountain wall of the Alps.
