Beipiaognathus (meaning Beipiao jaw) is a dubious genus of coelurosaurian theropod from the Early Cretaceous Yixian Formation of Liaoning, China. The type species is Beipiaognathus jii and it was named and described by Hu et al. in 2016.
The genus was initially assigned to the Compsognathidae by Hu et al. (2016) based on the presence of two traits: fan-shaped dorsal neural spines and a robust I-1 phalanx on the hand. However, it also differs from other compsognathids in several ways: the teeth are unserrated and conical; the ulna is proportionally longer; the II-1 phalanx on the hand is longer and more robust; and the tail is much shorter.
