Emiliasaura (meaning "Emilia's lizard") is an extinct genus of iguanodontian ornithopod dinosaurs from the Early Cretaceous (Valanginian) Mulichinco Formation of Neuquén Province, Argentina. The genus contains a single species, Emiliasaura alessandrii, known from three individual specimens. Emiliasaura was initially described as a rhabdodontomorph. If this identification is correct, it would represent the oldest member of this clade and the first named from South America. However, a later analysis of rhabdodontomorphs failed to recover Emiliasaura within this clade, instead placing it as a styracosternan.
