Carcharodontosauria is a clade of theropod dinosaurs, known from the Late Jurassic to the Late Cretaceous. They are considered to be members of Allosauroidea.

Taxonomy
The family Carcharodontosauridae was erected by Ernst Stromer in 1931. The clade Carcharodontosauria was first erected by Benson, Carrano and Brusatte, 2010 to include Carcharodontosauridae, as well as the newly erected family Neovenatoridae, which included Neovenator as well as the newly erected clade Megaraptora. Carcharodontosauria is placed within clade Tetanurae as members of the group Allosauroidea.

Many later studies have doubted the placement of Megaraptora within Carcharodontosauria, placing them within Coelurosauria instead. The placement of several other supposed neovenatorids within Carcharodontosauria, such as Gualicho and Siats have also been questioned. Since the description of the group, several non-carcharodontosaurid or neovenatorid carchachodontosaurians have been recognised, including Lusovenator, Siamraptor and Veterupristisaurus.
