Rhabdodon is a genus of ornithopod dinosaur that lived in Europe approximately 72-69 million years ago in the Late Cretaceous. The genus contains a single species, R. priscus. It is similar in build to a very robust "hypsilophodont", though all modern phylogenetic analyses find this to be an unnatural grouping, and Rhabdodon to be a basal member of Iguanodontia. It was large amongst its relatives, measuring 4 m (13 ft) long and weighing 250 kg (550 lb), with some specimens possibly reaching up to 6 m (20 ft) long.
