Pterorhynchus was a genus of pterosaur from the mid-Jurassic aged Daohugou Formation of Inner Mongolia, China. The genus was named in 2002 by Stephen Czerkas and Ji Qiang. The type species is Pterorhynchus wellnhoferi. The genus name is derived from Greek pteron, "wing" and rhynchos, "snout", in reference to the tall crest on the head. The specific name honours the German pterosaur researcher Peter Wellnhofer.
