Dorypterus is a small, extinct genus of prehistoric marine ray-finned fish. It lived during the Wuchiapingian stage of the late Permian epoch in what is now Germany (Kupferschiefer) and England. Indeterminate remains are known from Hunan, China. It is a hypsisomatic bobasatraniiform with a high dorsal fin. Due to anatomical differences with other bobasatraniiforms, such as the presence of pelvic fins and the reduced scale cover, Dorypterus is placed in its own monotypic family, Dorypteridae.
