Valosaurus ("Weald Lizard") is a genus of small, bipedal herbivorous ornithopod dinosaur found on the Isle of Wight, elsewhere in Europe, and Africa. It lived during the Early Cretaceous. The type species, V. canaliculatus, was described in 1975 by Peter Galton as a species of Dryosaurus, but he later gave it its own genus. A second species, V. nigeriensis is known from Niger, but is based on partial fossils. Valdosaurus was an iguanodont.
