An ursid hybrid is an animal with parents from two different species or subspecies of the bear family ("Ursidae"). Species and subspecies of bear known to have produced offspring with another bear species or subspecies include black bears, grizzly bears and polar bears, all of which are members of the genus "Ursus". Bears not included in "Ursus", such as the giant panda, are expected to be unable to produce hybrids with other bears. Note all of the confirmed hybrids listed here have been in captivity (except grizzly × polar bear), but suspected hybrids have been found in the wild.
