Sinraptor () is a genus of metriacanthosaurid theropod dinosaur from the Shishugou Formation China. Sinraptor and its close relatives were among the earliest members of the Jurassic carnosaurian radiation. Sinraptor still remains the best-known member of the family Metriacanthosauridae, with some older sources even using the name “Sinraptoridae” for the family.
