Nagaland Nationalist Organisation was a political party in Nagaland, India. It formed the government in Nagaland from 1964 to 1974.
Nagaland was converted to a state by the State of Nagaland Act, 1962 and elections were called for in 1964. There were no political parties registered for the first elections and so all the candidates, many of whom were members of the Nagaland National Organisation (NNO), contested as Independents.
In 1976, NNO merged with the Indian National Congress.
