Dinosauromorpha are a clade of archosaurs that includes dinosaurs and other closely related animals. Birds are the only surviving dinosauromorphs.

The name was coined by Michael J. Benton in 1984. The first clade definitions were by Paul Sereno in 1991. He defined the concept as:

The last common ancestor of Lagerpeton chanarensis, Marasuchus lilloensis, Pseudolagosuchus major and the Dinosauria (including Aves) and all its descendants.[1]

Another term, with somewhat different coverage is Avemetatarsalia.
