Zizhongosaurus (meaning "Zizhong lizard") is a genus of basal herbivorous sauropod dinosaur which lived in the Early Jurassic Period of China. It was a large-bodied herbivore characterized by a long neck.

The type species Zizhongosaurus chuanchengensis was named in 1983 by Dong Zhiming, Zhou Shiwu and Zhang Yihong; the generic name is derived from Zizhong County in Sichuan Province. The specific name refers to the town of Chuancheng.

The type specimens consist of three syntypes: V9067.1 is a partial dorsal vertebra; V9067.2 is a humerus or upper arm; and V9067.3 is a pubis. All specimens likely were part of a single skeleton. Zizhongosaurus was described as a small species.[1]

In 1999 Li Kui mentioned a second species: Zizhongosaurus huangshibanensis[2] but this has remained an undescribed nomen nudum.

Zizhongosaurus was originally assigned to the Cetiosaurinae but later authors have placed it in either the Vulcanodontidae, as a relative of Barapasaurus, or the Shunosaurinae, it is today often considered a nomen dubium.
