Abelisauroids are theropod dinosaurs in the clade Abelisauroidea within the clad Ceratosauria. Some well-known dinosaurs of this group include the abelisaurids Abelisaurus, Carnotaurus, and Majungasaurus.

Abelisauroids flourished in the Southern Hemisphere during the Cretaceous period, but their origins can be traced back to at least the Middle Jurassic, when they had a more global distribution (the earliest known abelisauroid remains come from Australian and South American deposits dated to about 170 million years ago). By the Cretaceous period, abelisauroids had apparently become extinct in Asia and North America, possibly due to competition from tyrannosauroids. However, advanced abelisauroids of the family Abelisauridae persisted in the southern continents until the Cretaceous–Paleogene extinction event 66 million years ago.
