Distribution of Deori-Chutiya Language in Upper Assam, as reported in the Language Survey of India 1903

Deori (also Deuri) is a Tibeto-Burman language in the Tibeto-Burman languages family spoken by the Deori people of Assam and Arunachal Pradesh.^[2] Deori are also a part of Bodo–Kachari people. Among the four territorial groups only the Dibongiya have retained the language. The others—Patorgoyan, Tengaponiya, and Borgoyan—have shifted to Assamese. It is spoken in Lohit district of Arunachal Pradesh, and in Lakhimpur, Dhemaji, Tinsukia, Sivasagar and Jorhat districts of Assam. The primary literary body of Deori is known as "deori chucheba chengcha" (Deori sahitya sabha).

In the colonial times this language became associated with the Chutia people erroneously,^[3] and came to be known as the "Chutia language" in the Linguistic Survey of India.^[4] Modern scholarship do not associate the Deori language with the Chutia community.^[5]

The Deori language is one of the most influential languages which has helped develop the Assamese language in Upper Assam. ^{[citation needed]}

However, the word for water has a similar form in many other languages of the Sal branch of Sino-Tibetan to which Deori belongs, so it is not conclusive evidence that Deori speakers were the first to occupy this area.^[6]
