Georgia is bordered on the south by Florida; on the east by the Atlantic Ocean and South Carolina; on the west by Alabama and by Florida in the extreme southwest; and on the north by Tennessee and North Carolina. The northern part of the state is in the Blue Ridge Mountains, a mountain range in the vast Appalachian Mountains system. The central piedmont extends from the foothills to the fall line, where the rivers cascade down in elevation to the continental coastal plain of the southern part of the state. The highest point in Georgia is Brasstown Bald, 4,784 feet (1,458 m); the lowest point is sea level.

With an area of 59,425 square miles (153,909 km²), Georgia is ranked 24th in size among the 50 U.S. states. Georgia is the largest state east of the Mississippi River in terms of land area, although it is the fourth largest (after Michigan, Florida, and Wisconsin) in total area, a term which includes expanses of water claimed as state territory.
