The Duna–Pogaya (Duna–Bogaia) languages are a proposed small family of Trans–New Guinea languages in the classification of Voorhoeve (1975), Ross (2005) and Usher (2018), consisting of two languages, Duna and Bogaya, which in turn form a branch of the larger Trans–New Guinea family. Glottolog, which is based largely on Usher, however finds the connections between the two languages to be tenuous, and the connection to TNG unconvincing.
