Smilosuchus (from Ancient Greek σμίλη (smílē), meaning "knife, chisel", and Σοῦχος (Soûkhos), meaning "Sobek") is an extinct genus of leptosuchomorph parasuchid phytosaurs from the Late Triassic of North America. Three species have been named: the type species S. gregorii, S. adamanensis, and S. lithodendrorum, all recovered from the Norian-aged Chinle Formation of Arizona.
