Quercus oglethorpensis (also called Oglethorpe oak) is a species of plant in the beech family.

[2] The county, in turn, is named for James Oglethorpe, the founder of Georgia Colony in the 18th century.

[3] Quercus oglethorpensis is a tree growing to approximately 25 meters (83 feet) in height, with a diameter at breast height of about 80 centimetres (31 inches).

The leaves are narrowly elliptical, up to 15 cm (6 in) long, usually flat rather than cupped, usually with no lobes.

[4][5] Quercus oglethorpensis is endemic to the southeastern United States, found only in the Piedmont of Georgia and South Carolina, and in Alabama, Louisiana and Mississippi.
