Dinaelurus is a genus of the Nimravidae, an extinct family of feliform mammalian carnivores, also known as "false saber-toothed cats".

Assigned to the subfamily Nimravinae, Dinaelurus was endemic to North America during the Oligocene epoch (30.8—20.6 mya), existing for approximately 10.2 million years.

Dinaelurus had a skull extremely broad for its length and had conical teeth; it exhibited little or no development of sabertooth features and had more rounded cheek teeth with no serrated ridges.

This is suggested by the nimravid's short face[4] and large nostrils, similar to those of a cheetah, which is also a cursorial predator.
