Ridgeland is home to the Ridgeland Correctional Institution, a medium-security prison operated by the South Carolina Department of Corrections.
Ridgeland was originally known as "Gopher Hill" in 1894, derived from the gopher tortoise, which is indigenous to the area. The name was not considered good enough for a new railroad station, so it was changed to "Ridgeland" in 1902 for the fact that the town stands on a sandy ridge that is some of the highest land in Jasper County.
Ridgeland is in northeastern Jasper County, with the center of town sitting on a low ridge at an elevation of 62 feet (19 m) above sea level. According to the United States Census Bureau, the town has a total area of 44.7 square miles (115.8 km2), of which 44.4 square miles (115.1 km2) are land and 0.3 square miles (0.7 km2), or 0.59%, are water. The town's area as of 2010 was 18 times greater than its 2000 area of 2.4 square miles (6.3 km2). The town limits now extend east into Beaufort County as far as the west bank of the Broad River.
