The Rajbanshi, also Rajbongshi and Koch-Rajbongshi,[11] are peoples from Lower Assam, North Bengal, eastern Bihar, Terai region of eastern Nepal, Rangpur division of North Bangladesh and Bhutan[12] who have in the past sought an association with the Koch dynasty.[13] Koch-Rajbanshi people speak Kamatapuri,[14] an Indo-Aryan language, likely due to language shift, and in the past they might have spoken Tibeto-Burman languages. The community is categorised as OBC in Assam and Bihar, and SC in West Bengal.[15] In Nepal they are considered part of the Plains Janjati. In Bangladesh the community is classified as Plains ethnic group under 'Barman'. They are the largest Scheduled Caste community of West Bengal.[16]
In 2020, Kamatapur Autonomous Council has been created for socio-economic development and political rights of Koch-Rajbongshi community residing in Assam.[17]
They are related to the ethnic Koch people found in Meghalaya but are distinguished from them as well as from the Hindu caste called Koch in Upper Assam that receives converts from different tribes.[18] Rajbanshi (of royal lineage) alludes to the community's claimed connection with the Koch dynasty.[13]

^"The Rajbanshi as a social and cultural group are well-known to historians, sociologists and anthropologists working on northeast India. They are also familiar to those who focus on the issues surrounding minorities and indigenous groups (compare Berlie, 1982; Bessaignet, 1964; Shrestha, 2009; Wilson, 2012). A sizeable population, they are mostly concentrated in the northern parts of West Bengal and western Assam in India, in northwest Bangladesh, and the Jhapa and Morang Districts of Nepal. Although this article focuses primarily on those living in northeast India, and despite variations identified in the anthropological literature, Rajbanshi inhabiting Nepal and Bangladesh (also Bhutan and Tibet) very likely share a common historical consciousness and folklore with theirIndian kin (Das, 2009)."(Wilson & Bashir 2016:457)

^An early investigation of Rajbanshi language appears in the Linguistic Survey of India, published by Grierson during the colonial period...Accordingly, Das sees no value (beyond the political) in considering Rajbanshi (or Kamtapuri/Kamata, as it is also called) as a distinct dialect.(Wilson & Bashir 2016:460)
