Chuandongocoelurus (Template:PronEng chwahn-DONG-o-see-LOOR-us - Chuandong and Greek Coelurus - koilos meaning "hollow" and oura meaning "tail") named after the Chuandong in Sichuan Province, China, was a genus of theropod dinosaur first described by Chinese paleontologist He in 1984. The formation in which it was discovered was the Lower Shaximiao Formation, part of the Dashanpu Formation, meaning Chuandongocoelurus dates to the Bathonian or Callovian stage of the Middle Jurassic.

Chuandongocoelurus is known from a single partial skeleton, mostly from the torso and pelvic regions. The specimen has unfused neurocentral sutures in its vertebrae, meaning that the animal was immature at the time of death.
