Dryosaurus (/ˌdrəˈsɔːrəs/ DRY-ə-SOR-əs, berarti 'kadal pohon', dari Yunani δρῦς (drys) berarti 'pohon, ek', σαυρος (sauros) 'kadal'; namanya merefleksikan habitat hutan dari

dinosaurus ini, bukan merujuk kepada gigi pipinya yang secara rancu berbentuk daun ek seperti yang terkadang dianggap orang) adalah genus dari dinosaurus ornithopoda yang hidup pada periode Jura Akhir. Dryosaurus merupakan anggota dari Iguanodontia (sebelumnya diklasifikasikan sebagai anggota Hypsilophodontiae). Fosil dari genus ini sudah ditemukan pada Amerika Serikat barat, dan pertamakali ditemukan pada akhir abad ke-19. Valdosaurus canaliculatus dan Dysalotosaurus lettowvorbecki awalnya dianggap sebagai spesies dari Dryosaurus.[1][2][3]

Bedasarkan spesimen yang diketahui dari Dryosaurus, paleontolog mengestimasikan panjang dari dinosaurus ini dapat mencapai 3 meter dan berat 100 kilogram.[4] Namun karena belum pernah ditemukan spesimen dewasa, paleontolog masih belum mengetahui pasti ukuran dewasa dari dinosaurus ini.[5]
