The Tanggula (Chinese: 唐古拉山, p Tánggǔlāshān, or 唐古拉山脉, p Tánggǔlāshānmài), Tangla, Tanglha, or Dangla Mountains (Tibetan: གདང་ལ་།, w Gdang La, z Dang La) is a mountain range in the central part of the Qinghai-Tibet Plateau in Tibet.

[1] Administratively, the range is in the Nagqu Prefecture of the Tibet Autonomous Region, with the central section extending into the Tanggula Town and the eastern section entering the Yushu Tibetan Autonomous Prefecture of Qinghai province.

The Yangtze River originates in this mountain range; Geladandong, 6,621 metres or 21,722 feet high, located in Tanggula Town, is the tallest peak in the range.

[4] On account of snow and occasional road accidents, highway closures and concomitant traffic delays are not uncommon.

[5] The mountains lie within the Tibetan Plateau alpine shrub and meadows ecoregion.
