Iguanodon (meaning "iguana-tooth"), named in 1825, is a genus of ornithopod dinosaur that existed roughly halfway between the first of the swift bipedal hypsilophodontids of the mid-Jurassic and the duck-billed dinosaurs of the late Cretaceous. Iguanodon were large, bulky herbivores. Distinctive features include large thumb spikes, combined with long prehensile fifth fingers able to forage for food. In early restorations, the spike was placed on the animal's nose. Later fossils revealed the true nature of the thumb spikes, although their exact function is still debated.

The genus was named in 1825 by English geologist Gideon Mantell but discovered by William Harding Bensted, based on fossil specimens found in England and was given the species name I. anglicus. Iguanodon was the second type of dinosaur formally named based on fossil specimens, after Megalosaurus.

As one of the first scientifically well-known dinosaurs, Iguanodon has occupied a small but notable place in the public's perception of dinosaurs, its artistic representation changing significantly in response to new interpretations of its remains.
