Linlongopterus is a genus of pteranodontoid pterodactyloid pterosaur from the Early Cretaceous of China.

The only known specimen was found in the Jiufotang Formation of the Liaoning Province or China, and lived around 120 million years ago.

The full binomial of the taxon is Linlongopterus jennyae, with the generic name translating from the Chinese "forest" (lin) and "dragon" (long), and the Greek "wing" (pteros), while the species name honours Elfriede Kellner, nicknamed Jenny, a supporter of paleontology.

The taxon was located within Dsungaripteroidea (sensu Kellner), which included Azhdarchoidea, Dsungaripteridae, and Pteranodontoidea, all of which were mostly dissolved due to the few remains known from Linlongopterus.

The taxon does not have the crests on its jaws, which excludes it from derived Anhangueridae, leaving a position basal within Anhangueria most likely.
