The Grünhorn (or Gross Grünhorn) (4,044 m) is a mountain in the Bernese Alps range of the Swiss Alps. It is located on the ridge between the two largest glaciers of the Alps: the Aletsch Glacier to the west and the Fiescher Glacier to the east. To the south lies the Gross Wannenhorn and, to the north, the Gross Fiescherhorn.
The first ascent was made on August 7, 1865 by the Bernese mineralogist Edmund von Fellenberg with guides Peter Michel, Peter Egger and Peter Inäbnit. They climbed the mountain from the west side, starting at the Ewigschneefeld, a tributary glacier of the Aletsch Glacier. They successfully reached the summit despite very bad weather conditions. The same climbers had made an attempt on the peak in the previous year, but they could only reach a lower prominence of the Grünegghorn.
A route on the north-east ridge was opened on 26 August 1913 by D. von Bethmann-Hollweg and O. Supersaxo. In the summer of 1950, G. Van der Leck climbed the west face. The western pillar was finally climbed by C. Blum and U. Frei on 27 August 1967.
