Deinonychus est un genre fossile de dinosaures carnivores de la famille des Dromaeosauridae, dont une seule espèce est connue, Deinonychus antirrhopus. Ce dinosaure long d'approximativement 3,40 mètres a vécu au Crétacé inférieur, entre environ 115 et 108 millions d'années. Ses fossiles ont été découverts dans les États américains du Montana, du Wyoming, de l'Utah et de l'Oklahoma, dans les roches des formations de Cloverly et d'Antlers. Des dents qui pourraient appartenir au genre Deinonychus ont été trouvées beaucoup plus à l'est dans le Maryland.
