Szechuanosaurus ("Szechuan lizard") is an extinct genus of carnivorous theropod dinosaur from the Late Jurassic. Fossils referred to the genus have been found in China, Asia in the Oxfordian-?Tithonian (Peng et al., 2005).^[1] Its type species is based on several undiagnostic teeth from the Kuangyuan Series.^[2]^[3] Additional possible specimens of Szechuanosaurus were also reported from the Kalaza Formation,^[4] also located in China.

Szechuanosaurus is at times regarded as a nomen dubium^[5]^[6] due to the lack of diagnostic features in the fossilized teeth upon which the genus is based.^[7] Although the fossils are too fragmentary for confident identification, Szechuanosaurus is often interpreted as a medium-sized allosaurid^[8] or perhaps a metriacanthosaurid,^[6] capable of reaching lengths of around 7.3 meters.^[6]
