Harpagolestes ("hooked thief") is an extinct genus of hyena like, bear sized mesonychid mesonychian that lived in Central and Eastern Asia and western and central North America during the middle to late Eocene.

[2] Harpagolestes was a large animal, with a skull length of a half a meter in some species.

[3] Fossil specimens have been recovered in the United States, Canada, Mongolia, China, and controversially North Korea.

[1] Harpagolestes exhibits strong, curved canine teeth, a deep lower jaw, massive skull, and heavy wear on the molars.

This along with stout limb bones suggest that Harpagolestes was a scavenger and did not pursue its prey.
