Chuandongocoelurus is an extinct genus of tetanuran theropod dinosaur from Jurassic China.
The type species Chuandongocoelurus primitivus was first described and named by Chinese paleontologist He Xinlu in 1984.
Chuandongocoelurus was based on two partial skeletons. The holotype, a thighbone, is part of specimen CCG 20010. Vertebrae, pelvic bones and hindlimb elements, also catalogued under this inventory number, may belong to the same individual. Chaundongocoelurus was a close relative of Elaphrosaurus.
A little known theropod dinosaur from China, a 2010 study by Benson et al found Chuandongocoelurus to probably be related to the more complete Monolophosaurus. The partial remains of Chuandongocoelurus are thought to be from a juvenile/subadult individual, and coupled with the overall incomplete nature of them, it is impossible to establish an accurate size estimate for this dinosaur.
