Pliosaurus was an extinct genus of gigantic plesiosaur from the late Jurassic of Europe and South America. Their diet included fish, cephalopods, and marine reptiles.

Most European species of Pliosaurus grew to about 8 metres (26 ft) long and weighed about 5 metric tons (5.5 short tons). Some would have been the largest plesiosaurs of all time, more than 10 metres (33 ft) in length. Their teeth were triangular in cross section.
