"Yandusaurus" is a genus of hypsilophodontid dinosaur from the Bathonian age (middle Jurassic, approximately 169 to 163 mya) of China.

A fast-moving biped, "Yandusaurus" had four toes on each foot and five fingers on each hand. It was 1 meters (3 ft) to 1.6 meters (5 ft) in length, and around 0.3 meters (1 ft) in height, weighing around 7 kilograms (15 lb). One species ("Y. hongheensis") is known from two nearly complete skeletons. He and Cai (1983) and Paul (1992) identified a second species, "Y. multidens", which was later re-assigned to the genus "Agilisaurus" as "A. multidens", and subsequently placed in its own genus, "Hexinlusaurus".
