"Moabosaurus" (meaning "Moab lizard") is the informal name given to an as yet undescribed genus of dinosaur from the Early Cretaceous. It was possibly a camarasaurid sauropod, and was discovered in the Cedar Mountain Formation near Moab, Utah. The full binomial name, "Moabosaurus utahensis", first appeared in print in 2006, in a publication for the Gigantic Dinosaur Expo 2006. "Moabosaurus" is considered a nomen nudum, as it has not been formally described.
