Compsosaurus (meaning "elegant lizard"[1]) is an extinct genus of phytosaur, a crocodile-like reptile that lived during the Triassic.

The type species, Compsosaurus priscus, was named by American paleontologist Joseph Leidy in 1856,[2] although other sources say 1857.

[3][4][5] Compsosaurus may have been the same animal as the related Belodon.

Only four teeth are known, discovered in the Carnian-Rhaetian-aged coal fields of Chatham County, North Carolina (probably Red Sandstone Formation) and the New Oxford Formation of Pennsylvania.
