Mystriosuchini is an extinct tribe of derived phytosaurs in the clade Leptosuchomorpha. As with all other phytosaurs, mystriosuchins lived during Late Triassic. The name is derived from the genus Mystriosuchus.

Genera classified in Mystriosuchini include Coburgosuchus, Machaeroprosopus, Mystriosuchus, Nicrosaurus and Redondasaurus.[1][2] It includes the most ecologically divergent phytosaurs, the terrestrial Nicrosaurus[3] and the fully aquatic Mystriosuchus.[4]
