Siats is an extinct genus of large neovenatorid theropod dinosaur known from the Late Cretaceous Cedar Mountain Formation of Utah, US. It contains a single species, Siats meekerorum. S. meekerorum could be the first neovenatorid discovered in North America and the geologically youngest allosauroid yet discovered from the continent. However, recent phylogenetic analyses find that megaraptorans are either tyrannosauroids, allosauroids, or basal coelurosaurs. More recent studies indicate that megaraptorans like Siats were indeed carnosaurs and were also part of the Neovenatoridae, albeit, ones that evolved tyrannosauroid-like features through convergent evolution.
