"Pteropelyx" is a dubious genus of Late Cretaceous hadrosaurid dinosaur from the Judith River Formation of Montana, named by Edward Drinker Cope in 1889. Historically, several species were assigned to it, all based on extremely fragmentary remains, but there is no evidence to support these assignments. Most of these other species' remains likely belong to better-known hadrosaurs, such as "Lambeosaurus" and "Gryposaurus". It is probable that the type material of "Pteropelyx", a skeleton lacking a skull, is from "Corythosaurus" (making "Pteropelyx" its senior synonym) (Brett-Surman, 1989), but the lack of a skull makes such a synonymy impossible.
