Beipiaopterus is a genus of ctenochasmatid pterosaur (flying reptile) from the Lower Cretaceous Yixian Formation (Aptian) in the People's Republic of China. The genus was named in 2003 by Lü Junchang. The generic name is derived from Beipiao City in Liaoning Province and a Latinised Greek pteron, "wing". The specific epithet honours paleontologist Professor Chen Peiji. In 2005 a study of the wing membrane by SEM (Scanning Electron Microscope) was published, showing it had contained many blood vessels, which indicated a role in the thermoregulation.
