Leshansaurus is a genus of theropod dinosaur from the Mid to Late Jurassic Dashanpu Formation of what is now China. It was described in 2009 by a team of Chinese paleontologists. The type species is Leshansaurus qianweiensis. Fossils of Leshansaurus were discovered in strata from the Shangshaximiao Formation, a formation rich in dinosaur fossils. Li et al. referred this taxon to Sinraptoridae - a group of carnosaurian theropods, but it may it belong to Megalosauridae instead.
