Tanggulashan Town ("Tanggula Mountains Town"), officially called Tanggula Town, is a town in the southwest of Qinghai province, China. It forms the southern exclave of the county-level city of Golmud, in Haixi Mongol and Tibetan Autonomous Prefecture. Before the local administrative reform of 2005, it was known as Tanggula Township (唐古拉乡).
Tanggula Town is an administrative unit that occupies 47,540 square kilometres (18,360 sq mi) in the southwestern corner of Qinghai province. It borders on the Tibetan Autonomous Region in the south and west, and on Qinghai's Yushu Tibetan Autonomous Prefecture in the east and north. The western "panhandle" of Yushu Prefecture separates Tanggula Town from the rest of Haixi Prefecture, making it an exclave of Golmud City and of the Haixi Mongol and Tibetan Autonomous Prefecture.
Tanggula Town is around 500 kilometres (310 mi) away (straight-line distance) both from the central city of Golmud and from the town of Gyêgu, the seat of Yushu Prefecture, but it has practical road (and rail) connection only with the former.
