Omnivoropteryx (meaning "omnivorous wing") is a genus of primitive flying avialan from the early Cretaceous Upper Jiufotang Formation of China. The authors who described Omnivoropteryx, Stephen Czerkas and Qiang Ji, stated that their specimen closely resembles Sapeornis, but the pubis was longer and, since no skull was known for Sapeornis, they did not consider the two names synonyms. The later discovery of Sapeornis skulls shows that they were indeed similar to Omnivoropteryx. This may make Omnivoropteryx a junior synonym of Sapeornis, and the name may be abandoned.

==Classification== Czerkas and Ji created the family Omnivoropterygidae to contain the genus Omnivoropteryx, as well as the order Omnivoropterygiformes, though some scientists do not recognize taxa that contain only one genus. Paul Sereno, for example, considered the family Omnivoropterygidae to be invalid because it is redundant and was not given a phylogenetic definition.
