Zhongyuansaurus is a genus of ankylosaurian dinosaur from the Cretaceous of Ruyang, Henan, China. It is known from remains including skull, arm, pelvic, and tail bones. It is distinguished by characteristics such as a flat roof to the skull, a straight ischium, and the location of muscle attachments on the upper arm. The type species, Z. luoyangensis, was described by Xu and colleagues in 2007. Zhongyuansaurus was described by Xu et al. as a nodosaurid, but was reevaluated in 2008 by Kenneth Carpenter and colleagues as a shamosaurine ankylosaurid, a type of ankylosaurid lacking a tail club.
