Ctenothrissa is a prehistoric genus of ray-finned fish in the supposed order "Ctenothrissiformes". These Teleostei are only known from fossils. While they are sometimes included in the superorder Acanthopterygii or Protacanthopterygii, this is neither well-supported, nor is the monophyly of the "Ctenothrissiformes" robustly established. Indeed, it is quite likely that the supposed order is a paraphyletic assemblage of ancient moderately advanced Teleostei.
