Gephyrostegus is a genus of extinct gephyrostegid reptiliomorph amphibian. It was a small animal at 22 cm snout-vent length, of generally lizard-like build and presumably habit. It had large eyes and a large number of small, pointed teeth, indicating it was an active insectivorous hunter. The remains have been found in Nýřany, Czech Republic, dating from around 310 million years ago (upper Carboniferous).

Originally thought to have been a seymouriamorph, the phylogenetic position is uncertain, and now it is placed in the family Gephyrostegidae, together with the genus Bruktererpeton. Several phylogenetic studies indicate that Gephyrostegus is only distantly related to amniotes, more distantly than diadectomorphs, lepospondyls and seymouriamorphs were.
