Parastylephorus (lit. 'near Stylephorus') is an extinct genus of ray-finned fish in the family Stylephoridae, known from the Middle Eocene (Bartonian age) Pabdeh Formation of Iran. The genus contains a single species, Parastylephorus anatoides, known from a nearly complete, articulated skeleton. Before this species was described, the extant Stylephorus (the tube-eye) was the only described member of the Stylephoridae. As such, Parastylephorus represents the oldest—and only—fossil record of the family.
