Aspidorhynchus is an extinct genus of ray-finned fish from the Jurassic and Cretaceous periods. It was about 60 cm (2 ft) long.
It was a long, fast-swimming fish with tooth-lined, elongated jaws. The upper jaw was longer than the lower jaw, ending in a toothless spike. Aspidorhynchus looked superficially similar to the present day gar genus Lepisosteus. Its closest living relative is the bowfin.
