Brachyrostrans are theropod dinosaurs in the clade Brachyrostra (meaning "short snouts") within the family Abelisauridae. It includes the famous genera Carnotaurus, Abelisaurus, and Aucasaurus, as well as their close relatives from the Cretaceous Period of Argentina and Brazil, plus Caletodraco from France. The group was first proposed in an analysis conducted by Juan Canale and colleagues in 2008. They found that all South American abelisaurids described up to that point grouped together as a sub-clade of Abelisauridae, which they named based on the relatively unusual shape of their skulls (in comparison with other theropods). They defined the clade Brachyrostra as "all the abelisaurids more closely related to Carnotaurus sastrei than to Majungasaurus crenatissimus".

The category that shows all the brachyrostrans of the Jurassic Park franchise (including genetically-altered creatures containing brachyrostran DNA).
