Gurla Mandhata, Mountain summit in Ngari Prefecture, China

Gurla Mandhata is the highest peak of the Nalakankar Himal, a subrange of the Himalaya, in Burang County, Ngari Prefecture, Tibet. It rises to 7,694 meters and is the 34th-highest peak in the world. The standard ascent route climbs the western flanks via the Chaglung'mlungha Glacier to the summit plateau.

In 1905 T. G. Longstaff, with two alpine guides and six porters, reached about 7,000 m on the west face before an avalanche and heavy snow turned the group back; no summit above 7,000 m had yet been climbed. Herbert Tichy got to 7,100 m in 1935. The first ascent was made in May 1985 by a Sino-Japanese team led by Katsutoshi Hirabayashi via the north face.

The Tibetan name Naimona'nyi is built from naimo (medicinal herb), na (black) and nyi (slabs), giving "heaps of black medicinal slabs"; Chinese sources instead read it as "Mountain of Our Lady". The Chinese name 纳木那尼峰 is a transcription of the Tibetan with 峰, "peak", added. The Hindi name links the peak to King Mandhata of the Solar Dynasty, who passed here toward Lake Manasarovar.

Most teams reach the mountain by jeep from Lhasa or Kathmandu; an alternative starts at Simikot in Nepal's Humla district, follows the Karnali River north and crosses into Tibet at Sher, then continues by jeep through Taklakot (Burang) to base camp. The standard ascent climbs the Chaglung'mlungha Glacier on the western flanks to the summit plateau.

The 1905 attempt by T. G. Longstaff reached about 7,000 m before an avalanche and heavy snow forced a retreat; at the time no summit above 7,000 m had been climbed, so this height stood as a world altitude record. In 1955 Sydney Wignall's Welsh Himalayan Expedition was seized by Chinese soldiers before climbing and held for two months as suspected CIA spies.
