Stenonychosaurus (meaning "narrow claw lizard") is a genus of troodontid dinosaur from the Late Cretaceous of Alberta, Canada based on a foot, fragments of a hand, and some caudal vertebrae.

A 2017 description had redeemed the validity of Stenonychosaurus and had informalised the genus "Troodon", synonymising it with Latenivenatrix.
