Psilorhynchus is a genus of small, benthic ray-finned fish in the family Psilorhynchidae native to South Asia. This genus is the only member of its family. Many members of Psilorhynchus occur in rivers and streams with fast to swift currents, hence they are often referred to as torrent minnows. They are distributed in southern Asia, in the Indo-Burma region and the Western Ghats.
The genus is the sister group to the family Cyprinidae, and with that family the Psilorhynchidae makes up the superfamily Cyprinoidea, with all the other cypriniform families in the superfamily Cobitoidea.
