Nyegyi Kangtsang (also known as Katoie Gyang by Puroik people and Kra-Daadi by Nyishi people) is a mountain of the Eastern Himalayas located in East Kameng district of Arunachal Pradesh state of India on the border with Tibet.

The peak is referred as Katoie Gyang by the Puroik people and Kra-Daadi or Wapra Kra-Daadi by Nyishi tribes in East Kameng district of Arunachal Pradesh has an elevation of 7,047 m (23,120 ft).

Katoie Gyang is one of the highest mountains in Arunachal Pradesh. The Kameng or Kaming (as referred to by Nyishi people) or Katoie Kwa Pi as referred to by Puroik people, is one of the most important rivers in Arunachal Pradesh. The Kameng or Katoie Kwa Pi is fed by several glaciers such as Katoie Gyang Glacier on the eastern flank of Katoie Gyang. The northern flank of the mountain is drained by the Subansiri. It is one of the three major peaks of the Kangto massif.

On October 23, 1995 five members of an Indian expedition under the leadership of MP Yadav claimed to have succeeded in the first ascent of the Nyegi Kantsang over the northeast ridge. However, it was later found that the team reached a point about 600 meters below the main summit, and the peak is still unclimbed.
