The Kukis, also known as the Chin and sometimes as the Zomi, and in the state of Mizoram Mizo are a number of related Tibeto-Burman tribal peoples spread throughout the northeastern states of India, northwestern Burma, and the Chittagong Hill Tracts of Bangladesh. In Northeast India, they are present in all states except Arunachal Pradesh. This dispersal across international borders is mainly attributed to the British colonial policy.

The Kukis have Mongoloid features and are generally short-stature with straight black hair and dark brown eyes. Some fifty tribes of Kuki peoples of India are recognised as scheduled tribes. This tribe recognition is based on the dialect spoken and region.
