Asiatosaurus (meaning "Asian lizard") was a genus of herbivorous sauropod dinosaur which lived during the early Cretaceous. Its fossils have been found in China and Mongolia. It is known only from teeth, making it difficult to rely on information until more specimens are found to expand our knowledge.

The type species, A. mongoliensis, was described by Osborn, in 1924.[1] It was the first sauropod genus named from East-Asia. A. kwangshiensis was described by Hou, Yeh and Zhao, in 1975 based on teeth from the Napai Formation of Guangxi, China.[2] Both are now classified as nomina dubia.
