Pseudoxiphophorus is a genus of fish from the family Poeciliidae. The species in the genus were formerly considered to be in the genus Heterandria but workers found that most of the species were not closely related to the type species of that genus, Heterandria formosa, and seven species were transferred to the genus Pseudoxiphophorus. They are found in Central America.
