Rabha is a Sino-Tibetan language of Northeast India.

The two dialects, Maitori and Rongdani, are divergent enough to cause problems in communication.

Joseph writes that "the Kocha dialect, spoken along the northern bank of the Brahmaputra, is highly divergent and is not intelligible to a Rongdani or Maitori speaker" (page ix).

Joseph also writes that "The dialect variations between Rongdani and Maitori, both of which are spoken on the southern bank of the Brahmaputra, in the Goalpara district of Assam and belong to the northern slopes of Meghalaya, are minimal" (pages ix-x).

Joseph published a grammar of Rabha with Brill in their series Languages of the Greater Himalayan Region.
