Rhabdodon (meaning "fluted tooth") is a genus of ornithopod dinosaur that lived in Europe approximately 70-66 million years ago in the Late Cretaceous. It is similar in build to a very robust "hypsilophodont" (non-iguanodont ornithopod), though all modern phylogenetic analyses find this ("Hypsilophodontia/tidae") to be an unnatural grouping, and Rhabdodon to be a basal member of Iguanodontia.
