Heyuannia ("from Heyuan") is a genus of oviraptorid dinosaur that lived during the Late Cretaceous Period in China. It was the first oviraptorid found in that country; most others were found in neighbouring Mongolia. Two species are known: H. huangi, named by Lü Junchang in 2002; and H. yanshini, originally named as a separate genus Ingenia by Rinchen Barsbold in 1981 (and renamed to Ajancingenia in 2013 due to the preoccupation of Ingenia).
The type species, Heyuannia huangi, was named and described by Lü Junchang in 2002. The generic name refers to the city of Heyuan. The specific name honours Huang Dong, the director of the Heyuan Museum. The holotype, HYMV1-1, was discovered in Guangdong near Huangsha in layers of the Dalangshan Formation. It consists of a partial skeleton, including the skull. Six further skeletons were assigned as paratypes or referred to the species. Multiple other fossils have been found, including one which may retain possible reproductive organs. Thousands of eggs have also been uncovered at the site, some of them belonging to the genus and likely laid by Heyuannia.
