Fulengia is the name given to a genus of dinosaur from the Early Jurassic. It was a prosauropod or other basal sauropodomorph. Its fossils were found in China. The type species, Fulengia youngi, was described by Carroll and Galton in 1977. It is a nomen dubium, and may be the same animal as Lufengosaurus (from which it is anagramized). It was originally thought to be a lizard.
