Chuanqilong (meaning "legendary dragon") is a monospecific genus of basal ankylosaurid dinosaur from the Liaoning Province, China that lived during the Early Cretaceous (late Barremian to Aptian stage, 122.0 to 118.9 Ma) in what is now the Jiufotang Formation. The type and only species, Chuanqilong chaoyangensis, is known from a nearly complete skeleton with a skull of a juvenile individual. It was described in 2014 by Fenglu Han, Wenjie Zheng, Dongyu Hu, Xing Xu, and Paul M. Barrett. Chuanqilong shows many similarities with Liaoningosaurus and may represent a later ontogenetic stage of the taxon.
Chuanqilong was a medium-sized ankylosaur, with an estimated length of 4.5 metres (14.8 feet), although it has been suggested that it would have been larger due to the immature age of the type specimen. It had a triangular skull and a neck that was protected by bands of osteoderms known as cervical half rings. The rest of the body was covered in osteoderms and ossicles of various shapes and sizes. Unlike derived ankylosaurids, the end of its tail lacked a club. Like other ankylosaurids, it was quadrupedal with robust forelimbs and hindlimbs.
