Ursus is a genus in the family Ursidae (bears) that includes the widely distributed brown bears, the polar bear, and black bears. The name is derived from the Latin ursus, meaning bear.

A hybrid between grizzly bears and polar bears has also been recorded. Known commonly as a pizzly, prizzly, or grolar bear, the official name is simply "grizzly–polar bear hybrid".
