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.

As with most of northwestern Qinghai, Lenghu has an arid climate (Köppen BWk), with long, cold winters, and warm summers.
