Hatzegopteryx ("Hațeg basin wing") is a genus of azhdarchid pterosaur, known from incomplete remains found in Hunedoara County, Transylvania, Romania. The skull fragments, left humerus, and other fossilized remains indicate it was among the largest pterosaurs. The skeleton of Hatzegopteryx has been considered identical to the known remains of Quetzalcoatlus northropi. Q. northropi has not yet been properly described, and if it is not a nomen dubium, Hatzegopteryx is possibly its junior synonym.
