Chungkingosaurus, meaning “Chongqing lizard”, is a genus of stegosaur dinosaur from the Late Jurassic Period. It is located in the Upper Shaximiao Formation in what is now China. The type species, C. jiangbeiensis, was found near Chongqing, China in 1977. It was first described in 1983 by Dong Zhiming, Zhou Shiwu, and Chang Yihong.

This is one of the smallest stegosaurs known at about 10 to 13 feet long. It had at least 5 spikes on its tail. The skull was high and narrow. It had large, thick bony plates that started at the neck and continued in pairs down the back. It is not known how many of these plates existed on every Chungkingosaurus, but the type species collected had 14 pairs. It was a herbivore, like all stegosaurs.
