Gnathochromis is a small genus of cichlid fish endemic to the Lake Tanganyika basin in East Africa.

The two species are distantly related (G. permaxillaris close to other limnochromines; G. pfefferi close to the tropheines) and as presently defined Gnathochromis is polyphyletic.[1]
Species

There are currently two recognized species in this genus:[2]

Gnathochromis permaxillaris (L. R. David, 1936)
Gnathochromis pfefferi (Boulenger, 1898)
