Abor Hills

The Abor Hills is a region of Arunachal Pradesh in the far northeast of India, near the border with China. The hills are bordered by the Mishmi Hills and Miri Hills, and drained by the Dibang River, a tributary of the Brahmaputra.

During the British Raj, the hills had a reputation as a troublesome area, and military expeditions were sent against the residents in the 1890s. The region was administered as the Abor Hills District from 1948, with headquarters at Pasighat, but later reorganized into the Lower Dibang Valley and Lohit districts.
