The Dibongiyas are one of the territorial groups of the Deuri- Chutiyas of Assam. The Deuri-Chutiyas are ethnically affiliated to the great Tibeto-Mongolian tribes of the State. The other groups of the Deuri- Chutiyas are the Bargonyas, the Tengapaniyas and the Patargonyas. The last group has reportedly become almost extinct. These four groups again constitute the Deuri-Chutiya sub-division of the Chutiyas. Formerly they were a priestly section among the Chutiyas. They conducted magico- religious rituals in the royal temples of the Chutiya Kingdom. Now they are recognised by the Constitution of India as one of the scheduled tribes of Assam. They sparsely inhabit the districts of Lakhimpur, Dibrugarh, Sibsagar and Darrang.
