Bennettsville is a city located in the U.S. state of South Carolina on the Great Pee Dee River.

According to the 2010 census, Bennettsville has a population of 9,069.
According to the United States Census Bureau, the city has a total area of 6.2 square miles (16 km2), of which 5.6 square miles (15 km2) is land and 0.6 square miles (1.6 km2) (10.13%) is water.
The city of Bennettsville was founded in 1819 on the Great Pee Dee River and named after Thomas Bennett, Jr., then governor of South Carolina. The area was developed for short-staple cotton cultivation, dependent on the labor of enslaved African Americans. Many were brought to the upland area from the Lowcountry, carrying their Gullah culture with them. Others were transported from the Upper South by slave traders. This shift to cotton cultivation in the uplands was based on the development of the cotton gin, which made short-staple cotton, cotton with relatively short fibers, profitable. The advent of the gin in turn led to development of large cotton plantations throughout the Deep South.
In the same year, the S.C. General Assembly authorized the relocation of the courthouse from the eastern bank of the Great Pee Dee River to a more central location, selecting a 3-acre (12,000 m2) apple orchard located on a bluff above Crooked Creek.
