Allosauroidea is a superfamily or clade of theropod dinosaurs which contains three families — the Sinraptoridae, Carcharodontosauridae and Allosauridae. The oldest-known allosauroid, Sinraptor dongi, appeared in the Middle Jurassic (Bathonian stage) of China, and the latest-known survivors of the family are the carcharodontosaurids of the Late Cretaceous, Cenomanian stage). Allosauroids had long, narrow skulls, large orbits, three-fingered hands, and usually had "horns" or ornamental crests on their heads. The most famous and best understood allosauroid is the North American genus Allosaurus.

- Allosauroidea is a clade subdivided into three families — the Sinraptoridae, Carcharodontosauridae and Allosauridae. The taxon was originally proposed by Currie and Zhao (1993; p. 2079), then noted as an undefined stem-based taxon by Sereno (1997). Later, Sereno (1998; p. 64) provided a stem-based definition for the Allosauroidea, defining the clade as "All neotetanurans closer to Allosaurus than to Neornithes." Most recently, Holtz et al. (2004; p. 100) defined the Allosauroidea as "Allosaurus fragilis, Sinraptor dongi, their most recent common ancestor, and all of its descendants."

The oldest-known allosauroid, Cryolophosaurus, appears in the Early Jurassic (Pliensbachian) of Antarctica, and the latest-known survivor of the clade is Allosaurus fragilis (Late Jurassic, Tithonian). Allosauroids have long, narrows skulls, large orbits, three-digit hands, and usually have "horns" or ornamental crests on their heads. The most famous and best understood allosauroid is the North American genus Allosaurus.
