Lenghu (simplified Chinese: 冷湖行政区; traditional Chinese: 冷湖行政區; pinyin: Lěnghú Xíngzhèngqū) is an Administrative Committee in the northwest of Qinghai province, China, bordering Gansu to the north/northeast and Xinjiang to the northwest. It is under the administration of Haixi Mongol and Tibetan Autonomous Prefecture.
Lenghu borders Da Qaidam to the east, Mangya to the west, Aksai Kazakh Autonomous County (Gansu) to the north, and Ruoqiang County (Xinjiang) to the northwest, and is part of the northwestern Qaidam Basin in an area dotted frequently by yardangs.

It is the driest locale in the country, with only 16.1 mm (0.63 in) of precipitation annually, and it is not uncommon for months to pass by without any rainfall, though underground water resources are plentiful. The monthly 24-hour average temperature drops to −12.5 °C (9.5 °F) in January and rises to 17.1 °C (63 °F) in July, while the annual mean is 2.82 °C (37.1 °F); diurnal temperature variation is wide, averaging 17.4 °C (31.3 °F) annually. The area is also extremely sunny; with monthly percent possible sunshine ranging from 72% in July to 85% in October, the area receives 3,443 hours of bright sunshine annually.
