Mahālangūr Himāl (Nepali: महालङ्गूर हिमाल, Mahālaṅgūra himāla) is a section of the Himalayas in northeast Nepal and south-central Tibet of China extending east from the pass Nangpa La between Rolwaling Himal and Cho Oyu, to the Arun River. It includes Mount Everest, Lhotse, Makalu, and Cho Oyu — four of Earth's six highest peaks. On the Tibetan side it is drained by the Rongbuk and Kangshung Glaciers and on the Nepali side by Barun, Ngojumba and Khumbu Glaciers and others. All are tributaries to the Koshi River via Arun River on the north and east or Dudh Kosi on the south.
Mahalangur Himal can be divided into three subsections:
The Khumbu region of Nepal is the best known populated part of the Mahalangurs since it is on the access trail to the normal (South Col) route up Everest.
