Nuptse, Mountain summit in Sagarmatha Zone, Nepal.

Nuptse is a mountain in the Khumbu region of the Mahalangur Himal, Nepal, 2 km southwest of Mount Everest. Its main peak, Nuptse I, rises to 7,861 m as a steep, slightly tilted summit with a snow-and-ice upper face scored by vertical runnels and ridges, tan and grey rock showing through near the top and along the right side, and more brown and grey rock on the lower portion.

Dennis Davis and Sherpa Tashi completed the first ascent of the main peak on May 16, 1961, following the north ridge during a British expedition. This climb marked an important milestone in mountaineering exploration of the region.

Nuptse is Tibetan for "west peak", as it forms the western segment of the Lhotse-Nuptse massif. The name also reached everyday life: in 1992 The North Face introduced the Nuptse Jacket, inspired by the region's peaks and worn by New York school kids and rappers in the 1990s.

Climbing permits, specialized equipment, and extensive mountaineering experience are needed to reach the summit through established routes. Visitors should be ready for extreme altitude conditions and technically demanding climbing sections.

Nuptse's topographic prominence is only 319 metres, so despite its height it is not counted among the highest mountains. The name is Tibetan for "west peak", as it forms the western segment of the Lhotse-Nuptse massif. In 1992 The North Face introduced the Nuptse Jacket, named after the mountain, with a baffle construction that limited down shifting.
