Rangpuri or Rajbangshi is a Bengali-Assamese language spoken by the Rajbongshi people in Bangladesh and India, and Rajbanshi and Tajpuria in Nepal. Many are bilingual in either Bengali or Assamese.


Rangpuri goes by numerous names. In Bangladesh, these include Rangpuri, Bahe Bangla, Ancholit Bangla, Kamta, Polia. In India, there is Kamtapuri, Dutta, Rajbangsi, Rajbansi, Rajbanshi, Rajbongshi, Goalparia, surjapuri, Koch Rajbanshi. Another name of the language is Tajpuri. In Assam it is known as Kochrajbongshi. In Bihar it is known as Surjapuri.


The main dialects are Western Rajbanshi, Central Rajbanshi, Eastern Rajbanshi and Hill Rajbanshi (also known as Koch language).

The Central dialect has the majority of speakers and is quite uniform. There are publications in this language. The Western dialect has more diversity. Lexical similarity is 77 to 89% between the three dialects. The version spoken in the hills has some influence of the local tribal languages and differs quite a bit from the other three. Rajbonshi shares 48 to 55% of its vocabulary with Bengali, and 43 to 49% with Maithili and Nepali.
