Hmar is the name of one of the numerous Mizo/Kuki/Chin tribes of India, spread over a large area in the northeast. The Hmars belong to the Chin-Kuki-Mizo group of tribes, and are recognised as Scheduled Tribe under the 6th Schedule of the Constitution of India. They are a small community of less than 100,000 in Assam, although there are more in Manipur, Mizoram and Tripura .

Literally, Hmar means North or Northern people, as they are living north to the Lusei people. But this is hotly debated among the community itself. Some scholars are of the opinion that the word originated from the style of tying the hair knot on the head.
