Huanhepterus is an extinct genus of ctenochasmatid pterodactyloid pterosaur from the Late Jurassic-age Huachihuanhe Formation of Qingyang, Gansu, China. The genus was named by Dong Zhiming in 1982. The type species is Huanhepterus quingyangensis. The genus name refers to the Huang Jian (not the Yellow River or "Huang He", but a smaller tributary of the Jinghe River in Gansu), and combines it with a Latinized Greek pteron, "wing". The specific name refers to Qinyang County. Like Gnathosaurus, it may have used its tightly-packed, slender teeth to filter food from water.
