Gyrodus (from , 'curved' and 'tooth') is an extinct genus of pycnodontiform ray-finned fish that lived from the Middle Jurassic (Bajocian) to the Early Cretaceous (Barremian).
== Palaeobiology == Dental microwear indicates that Gyrodus planidens closed its jaw in a propalinal motion with the prearticular shearing against the vomer during the powerstroke rather than through purely vertical jaw movement.
