Jidapterus is a genus of chaoyangopterid pterosaur from the Aptian-age Lower Cretaceous Jiufotang Formation of Chaoyang, Liaoning, China.

The skull is toothless and relatively long, with a straight and very pointed beak, and a large hole where the antorbital fenestra is joined with the nostrils.

The eye sockets are small, and there is no crest along the lower jaw as seen in ornithocheiroids, although a short projection was present at the back of the skull.

[4] David Unwin assigned it to Tapejaridae without comment in The Pterosaurs: From Deep Time,[5] but later, in a collaboration with Lü, agreed that it belonged to another azhdarchoid group and was a close relative of Chaoyangopterus, placing both in the new family Chaoyangopteridae.

In their phylogenetic analysis, they recovered Jidapterus within the family Tapejaridae, more specifically within a subfamily called Chaoyangopterinae, sister taxon to both Chaoyangopterus and Shenzhoupterus.
