The Danuwar are an ethnic group indigenous to the inner Terai regions of Nepal.

Danuwars can be found throughout the hills and Terai regions of central and eastern Nepal but they mainly reside in Sindhuli and Udayapur district.

[5] There are various sub groups largely Rajhan, Kachhade, Rai-Danuwar and Tharu Danuwar.

Another theory suggest that it is derived from the Sanskrit Dronibar which signifies the plain land between the confluences of two rivers situated in the laps of the two hills.

According to the census of 2011, there were a total of 46,000 who considered Danuwar as their mother tongue.
