Nagqu, Nagchu in original Tibetan or Naqu (Chinese: 那曲; pinyin: Nàqū), also known as Nagchuka or Nagquka, is a town in northern Tibet, seat of the prefecture-level city of Nagqu, approximately 328 km (204 mi) by road north-east of the capital Lhasa, within the People's Republic of China.

"Nagchu (...) is an important stop on both the road and railway line between Qīnghǎi and Tibet.

"[1] At the time of the visit in 1950 of Thubten Jigme Norbu, the elder brother of Tenzin Gyatso the 14th Dalai Lama, Nagchukha[citation needed] was a small town with only a few clay huts[citation needed] but was also the headquarters of the District Officer, the Dzongpön.

It was on the main caravan route coming from Amdo to Central Tibet.

With all months having a mean temperature below 10 °C or 50 °F, due to the town's very high altitude, Nagqu has an alpine climate (Köppen: ET), with long, very cold and dry winters, and short, cool summers.
