Tyrannosaurus is a genus of coelurosaurian theropod dinosaur. The species Tyrannosaurus rex, often called T. rex or colloquially T-Rex, is one of the most well-represented of the large theropods. Tyrannosaurus lived throughout what is now western North America, on what was then an island continent known as Laramidia.

Tarbosaurus is a genus of tyrannosaurid dinosaur that flourished in Asia about 70 million years ago, at the end of the Late Cretaceous Period, considered to contain a single known species, Tarbosaurus bataar. Fossils have been recovered in Mongolia, with more fragmentary remains found further afield in parts of China

Albertosaurus is a genus of tyrannosaurid theropod dinosaurs that lived in western North America during the Late Cretaceous Period, about 70 million years ago.

Daspletosaurus is a genus of tyrannosaurid dinosaur that lived in western North America between about 79.5 and 74 million years ago, during the Late Cretaceous Period. The genus Daspletosaurus contains two species.

Alioramus is a genus of tyrannosaurid theropod dinosaurs from the Late Cretaceous period of Asia. It currently contains two species. 

Guanlong is a genus of extinct proceratosaurid tyrannosauroid from the Late Jurassic of China. The taxon was first described in 2006 by Xu Xing et al., who found it to represent a new taxon related to Tyrannosaurus. The name is derived from Chinese, translating as "crown dragon". 

Nanotyrannus (Greek for "Dwarf Tyrant") is a highly dubious genus of tyrannosaurid dinosaur.

Raptorex is a dubious genus of tyrannosaurid dinosaur. Its fossil remains consist of a single juvenile specimen probably uncovered in Mongolia, or possibly northeastern China. The type species is R. kriegsteini, described in 2009 by Sereno and colleagues.

Lythronax is a genus of tyrannosaurid dinosaur that lived in North America around 80.6–79.9 million years ago during the Late Cretaceous period.

Thanatotheristes is a genus of tyrannosaurid dinosaur from the Late Cretaceous of Laramidia, approximately 80.1-79.5 Ma. Thanatotheristes contains only one species, T. degrootorum, which may actually be the same animal as Daspletosaurus.

Zhuchengtyrannus is a genus of tyrannosaurid theropod dinosaur known from the Campanian stage of the Late Cretaceous of Shandong Province, China. It belongs to the tyrannosaurinae subfamily, and contains a single species, Zhuchengtyrannus magnus

Teratophoneus is a genus of tyrannosaurid dinosaur which lived during the late Cretaceous period in what is now Utah, United States, containing a single known species, T. curriei. It is known from an incomplete skull and postcranial skeleton recovered from the Kaiparowits Formation.
