Upper Dibang Valley (Pron:/dɪˈbæŋ/) is a district of Arunachal Pradesh named after the Dibang River or the Talon as the Mishmis call it. Although the Dibang Valley district is the largest district in the state with an area of 9,129 square kilometres (3,525 sq mi), it is the least populated district in India.
In June 1980, Dibang Valley district was created out of part of Lohit district. On 16 December 2011, Dibang Valley district was bifurcated into Upper Dibang Valley district and Lower Dibang Valley district.
The river originates in the mountains of China and flows through the length of the valley which is named after it. The capital of this district, Anini, is the northernmost district capital in Northeast India. This district contains the northernmost point of Northeast India.
