Navahopus is an ichnogenus of dinosaur footprint that was made by an indeterminate navahopodid sauropodomorph once thought to have been a prosauropod that was alive during the Early Jurassic in southwestern United States. Two ichnospecies are known: the type ichnospecies, N. falcipollex and a second species, N. coyoteensis. It is known from the Early Jurassic of Arizona, California and Utah.
