Paronychodon (meaning "beside claw tooth") was a theropod dinosaur genus. It is a tooth taxon, considered dubious because of the fragmentary nature of the fossils, which include "buckets" of teeth but no other remains. Teeth of the Paronychodon type have been reported from a wide variety of times and places, including the 65.5 million year old end-Cretaceous Lance Formation of Wyoming and the early Cretaceous Una Formation of Spain, dating to the late Barremian age 125 million years ago.
