Allendale County is a county in the U.S. state of South Carolina. As of the 2018 census estimates, the population was 8,903  making it the least populous county in South Carolina. Its county seat is Allendale.
Allendale County was formed in 1919 from southwestern portions of Barnwell County, along the Savannah River. It is the location of the Topper Site, an archeological excavation providing possible evidence of a pre-Clovis culture dating back 50,000 years. The site is near a source of chert on private land in Martin owned by Clariant Corporation, a Swiss chemical company with a plant there. The site, named after John Topper, a local resident who discovered it, has been under excavation by archeologists from the University of South Carolina for about one month a year since 1999, after an initial exploratory dig in the mid-1980s.
According to the U.S. Census Bureau, the county has a total area of 412 square miles (1,070 km2), of which 408 square miles (1,060 km2) is land and 4.3 square miles (11 km2) (1.0%) is water. The Savannah River forms the county's western border with Georgia.
Allendale is 62 miles from Augusta, Georgia; 73 miles from Savannah, Georgia; 87 miles from Columbia; and 90 miles from Charleston. Before interstate highways were built, Allendale had several motels, primarily serving travelers going between Northeastern states and Florida. Traffic that formerly traveled U.S. 301 through Allendale now uses Interstate-95.
