Tuensang (Pron:/ˌtjuːənˈsæŋ/) is a town in Nagaland, India. It is the headquarters of the Tuensang district, the easternmost and the largest district of Nagaland, bordering with Myanmar. The town was founded in 1947 for the purpose of administrating the erstwhile North Eastern Frontier Agency (NEFA) that comprised the present day Tuensang, Mon, Longleng and Kiphire districts. Nowadays, these four districts combined together are also known as Eastern Nagaland.
