Nangqên County, or Nangchen (Tibetan: ནང་ཆེན་རྫོང་།, Chinese: 囊谦县), is currently a county of the Yushu Tibetan Autonomous Prefecture and is the southernmost county-level division of Qinghai province, China, bordering the Tibet Autonomous Region to the south.

[citation needed] The county seat is Xangda, built in a side valley and on the right bank of the Dza Chu (upper reaches of the Mekong).

In 2000, the county's population amounted to 57,387 people, inhabiting a surface of 11,539 km2 (4,455 sq mi).

Memories of the Kingdom of Nangchen play a role in local politics, and among Tibetan refugees who came to India from the area.

Scholar Maria Turek reported that in 2015 she heard about “a man who went to various Tibetan communities in India, introducing himself as ‘the king of Nangchen’ not without some success, even though he had no credentials to prove his claim.”[4] A Yelpa Kagyu monastery, Tana Monastery (Jang Tana), was founded by Yelpa Yeshe Tsek in 1068.
