thumb|left|Extremely hypothetical life restoration Crosbysaurus is a genus of extinct archosauromorph that lived in the Late Triassic of Arizona, New Mexico, North Carolina, Texas, and Utah. It is known from the Chinle Formation and Dockum Group rock units from the southwestern United States.

Crosbysaurus was originally identified as an ornithischian dinosaur by Andrew Heckert when it was first described in 2004. Further work has shown that it is likely an archosauromorph based on the features of its teeth, and it may belong to Archosauriformes. The taxon is likely valid as it differs from other genera from the same region known from teeth like Revueltosaurus, Tecovasaurus, Krzyzanowskisaurus, Lucianosaurus, and Protecovasaurus.
