Akanthosuchus ("spine crocodile", referring to its dermal armor) is an extinct genus of alligatoroid crocodilian, and has been regarded as a possible alligatorine. Fossils are known from the Paleocene-aged Nacimiento Formation of the San Juan Basin in New Mexico, United States. The genus is represented by a partial skeleton and isolated osteoderms (bony armor). The osteoderms have been described as distinctive, including both spike-shaped and blade-shaped elements.
