Kileskus is a genus of tyrannosauroid dinosaur known from partial remains found in Middle Jurassic (Bathonian age) rocks of Krasnoyarsk Krai, Russia. Fossils recovered include the holotype maxilla, a premaxilla, a surangular, and a few bones from the hand and foot. The skull bones are similar to those of Proceratosaurus. The type species is K. aristotocus. Kileskus was named in 2010 by Averianov and colleagues. They performed a phylogenetic analysis and found it to be a basal proceratosaurid.
