Huaxiagnathus is an extinct genus of coelurosaurian theropod dinosaur from the Lower Cretaceous of China. The genus contains a single species, Huaxiagnathus orientalis, known from two immature individuals from the Yixian Formation. Huaxiagnathus may represent an earlier ontogenetic stage of the tyrannosauroid Sinotyrannus from the younger Jiufotang Formation.
