Ctenothrissa is a prehistoric genus of marine ray-finned fish in the order Ctenothrissiformes. It contains a number of species known from the Late Cretaceous (middle Cenomanian to early Turonian) of England and Lebanon.
The following species are known:
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. It has instead been suggested by some authors that the supposed order is a paraphyletic assemblage of ancient moderately advanced Teleostei; for example, the ctenothrissiform Aulolepis is found by some authors to be an aulopiform.
