Eolacertilia ("dawn lizards") is a proposed clade of extinct lepidosauromorph reptiles known from fossils dating to the Triassic period. Whether they are a natural group is uncertain, and some suggest they form a "wastebasket" taxon. Suggested members of the group are Paliguana and Kuehneosauridae, as other genera have been transferred to basal groups within Diapsida (such as Palaeagama and Saurosternon), Archosauromorpha (Tanystropheus), or elsewhere (Cteniogenys).
