Sinopliosaurus (meaning "Chinese more lizard") is a dubious genus of pliosauroid plesiosaur. (disputed Sinopliosaurus remains have been dated to the Toarcian age and were found in the Ziliujing Formation) One species, "S." fusuiensis, was later shown to be based on teeth from a spinosaurid theropod dinosaur which is now known as Siamosaurus. S. weiyuanensis was considered as a freshwater plesiosaur.

The holotype, IVPP V140, consists of three vertebrae and a tooth, discovered in a layer of the Lianmugin Formation (Tugulu Group).
