Priapichthys annectens is a species of freshwater fish. It is a member of the family Poeciliidae of order Cyprinodontiformes. It is the type species of the genus Priapichthys (though first described as Gambusia annectens). It is native to Costa Rica, primarily inhabiting brooks and streams with currents of low to high velocity. A carnivorous surface feeder, it occurs in shoals near the shoreline.

This species has the terminal, upward-facing mouth typical of surface feeders, and a protruding belly. It is of plain coloration with 6–12 dark vertical bars along its sides, and the intensity of the bars varies according to the geographical region of different populations. Males reach a maximum overall length around 4 cm, with females reaching about 6.5 cm.
