The Zinalrothorn (4,221 m) is a mountain in the Pennine Alps in Switzerland. Its name comes from the village of Zinal lying on the north side and from the German word Rothorn which means Red Peak. When it was first climbed in 1864 the mountain was known locally as Moming.
The Zinalrothorn is one of the high summits separating the Matter valley on the east and the Val d'Anniviers (or more precisely the Val de Zinal) on the west. The summit of the Weisshorn (4,505 m) is located 5 km to the north and the Dent Blanche 7 km to the west. At the western foot of the mountain lies the large Zinal Glacier and, on the northern side, the Moming Glacier. L'Epaule (the shoulder) is a minor summit lying at the base of the northern ridge. The villages of Täsch and Zermatt are the closest while Zinal on the north-west is located further (9 km).
