Dryosauridae was a family of primitive iguanodonts, first proposed by Milner & Norman in 1984.

They are known from Middle Jurassic to Early Cretaceous rocks of Africa, Europe, and North America.

[3][4][5][6][7] Under the Phylocode, Madzia et al. (2021) formally defined Dryosauridae as "the largest clade containing Dryosaurus altus but not Iguanodon bernissartensis.
