Nuptse or Nubtse is a mountain in the Khumbu region of the Mahalangur Himal, in the Nepalese Himalayas. It lies 2 km WSW of Mount Everest. The main peak, Nuptse I at an elevation of 7,861 m, was first climbed on May 16, 1961, by Dennis Davis and Sherpa Tashi. After a hiatus of almost 20 years, Nuptse again became the objective of mountaineers, with important routes being put up on its west, south, and north faces.
