The eastern gray squirrel (Sciurus carolinensis) is a tree squirrel native to the eastern an midwestern United States and to the southerly portions of the eastern provinces of Canada. The specific epithet, carolinensis, refers to the Carolinas, where the species was first recorded and where the animal is still extremely common. The native range of the eastern gray squirrel overlaps with that of the fox squirrel (Sciurus niger), with which it is sometimes confused, although the core of the fox squirrel's range is slightly more to the west.
