The name of the District is derived from the Subansiri River, a tributary of Mighty Brahmaputra, that flows through Raga Circle of this District. Till 1914, the District was a part of Lakhimpur District of Assam. By the Government of India Notification of 1914, the area covered by this District became a part of Lakhimpur Frontier Tract of the “North East Frontier Tract”. In March, 1919, by another public Notification, the Lakhimpur Frotier Tract along with Western sector was renamed as the “Balipara Frontier Tract”.

In 1946, the District area was curved out of the Balipara Frontier Tract in the name of “Subansiri Area” with its Headquarter at North Lakhimpur. In 1954, Subansiri Area was renamed as the “Subansiri Frontier Division” and its Headquarter was later transferred to Ziro. Like other parts of NEFA, the District was also under the Ministry of External Affairs and over-all Incharge was a Political Officer.

On 1st September, 1965, the Ministry of Home Affairs took over the Administrative charge of NEFA from the Ministry of External Affairs, and the Subansiri Frontier Division was renamed as Subansiri District, and Political Officer was redesignated as Deputy Commissioner, Addl.Political Officer as Addl. Deputy Commissioner, Assistant Political Officer(I) as Assistant Commissioner, Assistant Political Officer(II) as Extra Assistant Commissioner and Base Superintendent as Circle Officer respectively.

On 13th May’1980, Subansiri District was bifurcated into Lower and Upper Subansiri District. Upper Subansiri District was formed by covering the area of the then Daporijo Sub-Division, and rest of the area of erstwhile Subansiri District was placed under Lower Subansiri. Finally on the 22nd September, 1992, Lower Subansiri District was again bifurcated, and Papumpare District was formed.
