Caenagnathus ('recent jaw') is a genus of caenagnathid oviraptorosaurian dinosaur from the late Cretaceous period (Campanian stage; ~75 million years ago).

It is known from partial remains including lower jaws, a tail vertebra, hand bones, hind limbs, and pelvis, all found in the Dinosaur Park Formation of Alberta, Canada.

This fossil was used to link the discoveries of several fragmentary oviraptorosaur species into a single dinosaur, which was assigned to the genus Chirostenotes, originally named for a pair of hands that were long considered to come from the same animal as Caenagnathus.

[6] However, Senter and Parrish (2005) doubted the synonymy of Caenagnathus with Chirostenotes, noting that the maxillary remains included in the Epichirostenotes holotype didn't overlap with CMN 8776.

A cladistic analysis of Coelurosauria by Senter (2007) found Caenagnathus to fall basally within Caenagnathoidea, while Chirostenotes fell as a derived taxon related to Elmisaurus.
