Sinosaurus (meaning "Chinese lizard") was a tetanuran theropod dinosaur which lived during the Late Triassic or Early Jurassic Period. Its fossils were found in the Lufeng Formation, in Yunnan Province, China. It was a bipedal carnivore. There is currently insufficient information available to reliably estimate height and weight.

It was described in 1948, by Chinese paleontologist Chung Chien Young, from a maxilla (upper jaw) and teeth. Originally thought to be a coelophysoid related to Dilophosaurus, Rauhut (2000) showed to to be a more advanced theropod, related to Cryolophosaurus and "Dilophosaurus" sinensis.

The name should not be confused with Sinusonasus.
