The Mount Graham red squirrel (Tamiasciurus hudsonicus grahamensis) is a subspecies of the North American red squirrel (Tamiasciurus hudsonicus). The geographical distribution of the North American red squirrel ranges from Alaska, the Yukon, the Northwest Territories, and Quebec southward as far as the Rocky Mountains of New Mexico and Arizona in the west and the Appalachian Mountains of South Carolina in the east. The Mount Graham red squirrel, however, is found only in the Pinaleño Mountains of Graham County, Southeastern Arizona.
