Its fossils, a nearly complete skeleton including the skull, were found near the town of Jingshan, Lufeng County, Yunnan Province, China, from which the name derives. First described in 1995, the type species is J. xinwaensis, formalized by Zhang and Yang. Fossil remains of Jingshanosaurus had been exhibited in museums several years prior to the formal naming.

Classification
Jingshanosaurus may have been most closely related to Yunnanosaurus, and has, at times, been included in the Yunnanosauridae. In fact, Dong Zhiming considered Jingshanosaurus possibly a large specimen of Yunnanosaurus. If true, this would make Jingshanosaurus a junior synonym of Yunnanosaurus.
