Euronychodon ("European claw tooth") is the name given to a genus of coelurosaur dinosaur from the Late Cretaceous of Europe and Asia.

Paronychodon was originally described as similar to Zapsalis, another tooth taxon often considered synonymous with Richardoestesia (a possible dromaeosaurid).

It later had many different identifications: as a coelurid, an ornithomimosaur, a dromaeosaurid, an archaeopterygid and a troodontid — though it could also be another kind of coelurosaurian theropod.

While most researchers have therefore considered such taxa as representing simply indeterminate theropod teeth, a small consensus has found them to belong to the Deinonychosauria.

One study showed that the tooth enamel is identical to that found in Byronosaurus, a troodontid.
