Camposaurus (meaning "Charles Lewis Camp's lizard") is a coelophysoid dinosaur genus from the Late Triassic of North America. With fossils dating back to the early to middle Norian stage, it is the oldest known neotheropod. It is known from partial lower leg bones, holotype UCMP 34498, and other fragmentary material. Like other coelophysids, it has fused tibio-tarsals and fibula-tarsals. Unlike its relatives, the area of the tibia that fits with the fibula has a distinct ridge at the back. Another unique feature is the lack of a large medial condyle on the astragalus.
