Nimravides is a genus of extinct saber-toothed felids that lived in North America during the middle and late Miocene, between 13.6 and 4.9 Ma.[1] Despite its scientific name, Nimravides does not belong to the Nimravidae, but is a true felid, belonging to the family Felidae.[2]

The earlier species of the genus, like Nimravides pedionomus from Clarendonian deposits, are smaller and more primitive than later forms, like Nimravides catacopsis. The tiger-sized Nimravides catacopsis strongly resembles the primitive Machairodus aphanistus, a species known from the Late Miocene of Eurasia.[3]
