Oviraptoridae is a family of maniraptorian theropods closely related to the caenagnathids and therizinosaurs. They possessed toothless beaks and had a highly debated diet; it was originally thought to be of dinosaur eggs, but is now suspected to have been at least primarily herbivorous, though some may have been partly carnivorous. Some species had head crests and some didn't, though it does not appear as if these two groups formed a natural division within the family. Classification both within this family and within its superfamily, Caenagnathoidea, is somewhat uncertain.
- Ajancingenia yanshini (formerly "Ingenia", name preoccupied)
- Jiangxisaurus ganzhouensis (possible member)
- Rinchenia mongoliensis (originally species of Oviraptor)
