Jintasaurus is a genus of hadrosauriform dinosaur that lived during the Early Cretaceous of what is now Jiuquan, Gansu, northwestern China. The type species is J. meniscus, described by Hai-Lu You and Da-Qing Li in 2009. The holotype and only known specimen includes the postorbital skull, lacking the jugal and quadratojugal, whose discovery supports the theory that hadrosaurs originated in Asia.
