       Cathayornis is a genus of enantiornithine bird that lived in China during the early Cretaceous.‭ ‬While the type species of Cathayornis,‭ ‬C.‭ ‬yandica is valid,‭ ‬two further species C.‭ ‬aberransis and C.‭ ‬chabuensis have also been named but are questionable as they consist of partial‭ ‬body parts that are not preserved in with the type species,‭ ‬and so cannot be assigned without a degree of uncertainty.‭ ‬A further species called C.‭ ‬caudatus has been renamed as a distinct genus called Houornis,‭ ‬but this assessment too has been controversial.
