Mountain in the Pennine Alps, Switzerland

The Dom is a mountain of the Pennine Alps, located between Randa and Saas Fee in the canton of Valais in Switzerland. With a height of , it is the seventh highest summit in the Alps, overall. Based on prominence, it can be regarded as the third highest mountain in the Alps, and the second highest in Switzerland, after Monte Rosa. The Dom is the main summit of the Mischabel group (German: Mischabelhörner), which is the highest massif lying entirely in Switzerland. The Dom is noteworthy for its 'normal route' of ascent having the greatest vertical height gain of all the alpine 4000 metre peaks, and none of that route's 3,100 metres of height can be achieved using mechanical means. The former name Mischabel comes from an ancient German dialect term for pitchfork, as the highest peaks of the massif stand close to each other.

The Dom is the culminating point of a chain running from the Schwarzberghorn on the south, at the intersection with the main chain of the Alps (Alpine watershed), to the Distelhorn on the north and ending above the town of Stalden. The chain lies entirely in the district of Visp. The two valleys separated by the range are the Mattertal on the west and the Saastal on the east. The towns of Randa and Saas Fee lie both six kilometres from the summit (to the west and the east, respectively). The elevation difference between the summit and the valley floor is 3,150 metres on the west side (Randa) and 3,000 metres on the east side (Saas Grund). On the Mattertal side, the Dom faces the almost equally high Weisshorn and, on the Saastal side, it faces the Weissmies. The Dom is the highest point of the Saastal and the second highest mountain of the Mattertal after Monte Rosa. Since the Dom is not on the main Alpine chain, the rivers flowing on both the west and east side of the massif end up in the same major river, the Rhone, through the Mattervispa and the Saaservispa. The Dom is the highest mountain in the Alps with this peculiarity. The Mischabel group includes many subsidiary summits above 4,000 metres. To the north lies the Nadelgrat, composed of the Lenzspitze, the Nadelhorn, the Stecknadelhorn, the Hohberghorn and the Dürrenhorn. The Nadelgrat is easily visible from the north and gives the massif its characteristic pitchfork appearance. The second highest peak of the massif, the Täschhorn to the south, culminates at 4,491 metres, and south of it, is the characteristically flat summit of the Alphubel. In total, eight summits above 4,000 metres make up the Mischabel massif. Other important peaks of the massif are the Ulrichshorn and the Balfrin. The Dom has a western shoulder (4,479 m) and an eastern shoulder (4,468 m). Generally, areas above 3,000 metres are covered by glaciers, the two largest being the Ried Glacier situated at the foot of the Nadelgrat and the Fee Glacier, at the foot of the Dom itself, below the east face.

The massif is almost entirely composed of gneiss from the Siviez Mischabel nappe. The latter is part of the Briançonnais microcontinent and is located in the Penninic nappes.

The first ascent of the Dom was made on 11 September 1858. It was reached via the Festigrat (north west ridge) by John Llewelyn Davies with guides Johann Zumtaugwald, Johann Krönig and Hieronymous Brantschen. Davies published an account of his ascent in Peaks, Passes and Glaciers. The first ascent of the western ridge (above the Festikinlücke) was made in 1879 by two parties. One comprised Mrs E. P. Jackson with her guides Aloys Pollinger, Peter Josef Truffer and Josef Biner. The second consisted of Percy Thomas with Josef Imboden and Josef Lengen. They bypassed the upper section and traversed the west face to join the upper part of the Festigrat before arriving to the summit. The first complete ascent on the entire western ridge was made later in 1882 by Paul Güssfeldt and guides Alexander Burgener and Benedict Venetz.

Climbing the Dom by its normal route is a relatively straightforward, but nevertheless long and somewhat arduous 3,100 metre ascent on foot from the valley, and taking 6 hours to the summit from the Dom Hut. The route is graded as PD on the French adjectival climbing scale. This route has been described in the mountaineering literature as "something of a snow trudge". The only mechanical means of access is located in the Saas Fee area, on the east side of the mountain, from which all the routes to the Dom are much harder. Since the location is difficult to access, documentation remained scarce, and the condition of the plant was uncertain. As part of an art project, Swiss artist Sandro Steudler, together with mountain guide Alexander Kleinheinz and alpine photographer Caroline Fink, set out in July 2023 to search for the plant. Despite challenging conditions and snow on the ridge, Alexander Kleinheinz succeeded in finding the plant and placing a temperature sensor beneath it, which had been given to them beforehand by Christian Körner; Caroline Fink documented the location photographically. The sensor will record the temperature under the stonecrop until 2026. It is believed that this saxifrage grows in the coldest location in the world where a flowering plant has been found so far.
