Claorhynchus (meaning "broken beak", as it is based on broken bones from the snout region) is a dubious genus of cerapodan dinosaur with a confusing history behind it. It has been considered to be both a hadrosaurid and a ceratopsid, sometimes the same as Triceratops, with two different assignments as to discovery formation and location, and what bones make up its type remains.

==History== The holotype specimen, AMNH 3978, was described by American paleontologist Edward Drinker Cope in 1892, who interpreted it as the rostral bone and predentary of a member of Agathaumidae from the Laramie Formation of Colorado. It was reinterpreted as a hadrosaurid, though, by American paleontologist John Bell Hatcher in 1902 and removed as a ceratopsid. In 1904, Franz Baron Nopcsa reclassified it as a ceratopsid. In their influential monograph, Richard Swann Lull and Nelda E. Wright regarded the genus as a dubious type of hadrosaurid, based on premaxillae and a predentary.
