Jidapterus is a type of chaoyangopterid pterosaur discovered in the Jiufotang Formation of Chaoyang, Liaoning, China, dating back to the Aptian period of the Lower Cretaceous.

Jidapterus is represented by a mostly intact skeleton with a partially preserved skull. The toothless skull is elongated, featuring a straight and sharply pointed beak, along with a sizable opening where the antorbital fenestra connects with the nostrils. The eye sockets are relatively small, and unlike ornithocheiroids, there is no crest running along the lower jaw, although a small projection can be observed at the back of the skull. The estimated wingspan of this specimen is 1.7 meters (5.6 feet).

With its sharp, pointed beak, this creature was most likely a ground-dwelling predator, preying on small vertebrates in the forest. Unlike some azhdarchoids, it lacked a ridged crest along its skull, though it did have a small projection at the back.

The classification of this species, like many azhdarchoids, has been a subject of debate in the past. While some initially suggested a connection to pteranodontids, it is now established and well-founded as a member of Neoazhdarchia.
