List of Naga ethnic groups
Naga is an umbrella term for several indigenous communities in Northeast India and Upper Burma. The word Naga originated as an exonym. Today, it covers a number of ethnic groups that reside in the Indian states of Nagaland, Manipur, Assam and Arunachal Pradesh and also in Myanmar.

Before the arrival of the British, the term "Naga" was used in Assam to refer to certain isolated ethnic groups. The British adopted this term for a number of ethnic groups in the surrounding area, based on loose linguistic and cultural associations. 
Nagaland became the 16th state 
on 1 December 1965.
S. R. Tohring (2010) lists 66 Naga ethnic groups whereas Kibangwar Jamir (2016) lists 67 ethnic groups. The 1991 Census of India listed 35 Naga groups as Scheduled Tribes: 17 in Nagaland, 15 in Manipur and 3 in Arunachal Pradesh.
