Jaxartosaurus was a hadrosaur similar to Corythosaurus which lived during the Late Cretaceous. Its fossils were found in China. It had a large, helmet-like crest that it used to vocalize with members of the same herd. Females had the smallest crests, and juveniles had none at all.

The type species, J. aralensis, was first described by Riabinin in 1937. A second species, J. fuyunensis, was described by Weishampel and Horner in 1990, but is dubious.
