Colleton County is a county in the Lowcountry region of the U.S. state of South Carolina. As of the 2020 census, the population was 38,604.^[1] Its county seat is Walterboro.^[2] The county is named after Sir John Colleton, 1st Baronet,^[3] one of the eight Lords Proprietor of the Province of Carolina. After two previous incarnations, the current Colleton County was created in 1800.^[4]

In 1682, Colleton was created as one of the three original proprietary counties, located in the southwestern coastal portion of the new South Carolina Colony and bordering on the Combahee River.

In 1706, the county was divided between the new Saint Bartholomew and Saint Paul parishes. This area was developed for large plantations devoted to rice and indigo cultivation as commodity crops. The planters depended on the labor of African slaves transported to Charleston for that purpose. In the coastal areas, black slaves soon outnumbered white colonists, as they did across the colony by 1708.

In 1734, most of the coastal portion of Saint Paul's Parish was separated to form the new Saint John's Colleton Parish. In 1769, the three parishes were absorbed into the Charleston Judicial District, the southwestern portion of which was referred to as Saint Bartholomew's.

In 1800, the new Colleton District was formed from the western half of the Charleston District. In 1816, it annexed a small portion of the northwestern Charleston District.

In 1868, under the Reconstruction era new state constitution, South Carolina districts were reorganized as counties. Officials were to be elected by the resident voters rather than by state officials, as was done previously, thus giving more democratic power to local residents.

In 1897, the northeastern portion of the county was separated to form the new Dorchester County, with its seat at St. George.

In 1911, the portion of the county east of the Edisto River was annexed by Charleston County. In 1919 and again in 1920, tiny portions of northwestern Colleton County were annexed to Bamberg County.

In March 1975, the town of Edisto Beach was annexed to Colleton County from Charleston County, thus bringing the county to its present size.
