Namka Chu or Kejielang River ({{zh|c=克节朗河|p=Kè jié láng hé}}){{Cite book|url=https://books.google.com/books?id=PsoDGLNmU30C&pg=PA184|title = Chinese Warfighting: The PLA Experience Since 1949|isbn = 9780765610874|last1 = Ryan|first1 = Mark A.|last2 = Finkelstein|first2 = David Michael|last3 = McDevitt|first3 = Michael A.|year = 2003}}
is a tributary of Nyamjang Chu that flows along the disputed border between India and China. The Indian side of the border is the Tawang district in Arunachal Pradesh. The Tibetan side of the border is in Tsona Dzong, Shannan province of Tibet. Namka Chu originates near the trijunction of Tibet, Bhutan and India and flows east for 26 km before joining Nyamjang Chu. It is about 200 kilometers away from the Misamari railhead and 60 kilometers from the Tawang road head. The Namka Chu valley was the scene of some of the most fierce fighting during the 1962 Sino-Indian war.

The battle of Namka Chu began on 10 October 1962 and continued until 16 November of the same year. The Indian brigade was headed by Brig. John Dalvi.{{cite web|url=http://www.indiandefencereview.com/the-battle-of-tawang/|title=The Battle of Tawang|publisher=|date=5 September 2015|accessdate=1 August 2017}}
It concluded with the total destruction of 7 Brigade of the Indian Army and the capture of Dalvi, who was repatriated in 1963. His book Himalayan Blunder is a detailed analysis of the prelude and conduct of the battle from the Indian point of view. The Indian defeat at the Nam Ka Chu was the first in the India-China border war of 1962, which ended with a unilateral Chinese ceasefire and withdrawal after China had captured almost the entire disputed territory of NEFA (now Arunachal Pradesh).
