Liaoningopterus, sometimes misspelled as "Liaoningopteryx", was a genus of anhanguerid pterodactyloid pterosaur from the Barremian-Aptian-age Lower Cretaceous Jiufotang Formation of Chaoyang, Liaoning, China.

The specific name honors Professor Gu Zhiwei, an invertebrate specialist who has pioneered the study of the Jehol Biota.

The genus is based on holotype IVPP V-13291, a crushed partial skull and skeleton including the jaws, teeth, a cervical vertebra, and bones of the finger supporting the wing.

It was a large pterosaur with skull alone estimated at 61 cm (24 in) long, bearing low crests close to the tip of the beak on both lower and upper jaws.

Tooth length in the specimen is very variable, which the authors explained by the presence of recently erupted replacement teeth.
