Pogonichthys, the splitails, is a genus of freshwater ray-finned fish belonging to the family Leuciscidae, the shiners, daces and minnows. These fishes are native to western North America.
The common name is inspired by the distinctive appearance of the tail fin, in which the upper lobe is distinctly larger.
Of the two species, only the Sacramento splittail survives; the Clear Lake splittail became extinct in the mid-1970s.
