Aphyocheirodon is a monospecific genus of freshwater ray-finned fish belonging to the family Cheirodontinae.

The only species in the genus is Aphyocheirodon hemigrammus, a characin, which is endemic to Brazil, and has a highly restricted range in the upper basin of the Paraná River, being found in the Rio Grande in São Paulo and Minas Gerais, and in the Mogi-Guaçu River in São Paulo.[2] This species occurs in shallow lagoons with a mean depth of 3 m (9.8 ft), with a mixed substrate of mud and sand where there is abundant aquatic vegetation. It can also be found in lower-order streams with rapids and backwaters. Floodplain drainage and landfilling have been observed to cause a decline in the quality of habitat.[1]

This species has a maximum total length of 15 cm (5.9 in).[3]
