Le Metriacanthosaurus, qui signifie « reptile modérément épineux », est un genre de dinosaure au sous-ordre des théropodes (Theropodae) de la super-famille des sinraptoridés qui a vécu au Jurrassique, période géologique qui s’étend de -199,6 ± 0,6 à 145,5 ± 4,0 Ma et plus précisément à l'Oxfordien. Carnivore, il pouvait mesurer 8 m de long, de 2 à 3 m de haut et peser 1 tonne. La première découverte fossile de ce dinosaure a été réalisée par le célèbre paléontologiste allemand Friedrich von Huene en 1923 au sud du Royaume-Uni.
