Kingstree is a city and the county seat of Williamsburg County, South Carolina, United States. The population was 3,328 at the 2010 census.
The original town was laid out as Williamsburg by the Lords Proprietors in colonial times, but a lone, unusually large white pine was found along the Black River. Since tall white pines were ideal for use as masts for ships, it was claimed by the Crown on behalf of the king. The broad arrow mark was carved into the tree to prevent any colonists from cutting it. Though white pines are native to the Appalachians as far south as Georgia, it is the only tree of King George’s ever found in the South. Over time, the county kept the name Williamsburg, but the county seat became known as the King's Tree, giving rise to its modern name.
General Francis Marion, known as the Swamp Fox, defeated the British at the Battle of the Lower Bridge in March 1781. A historical marker between US Highway 521 and the Black River denotes the battle.
After the British had captured Charles Town during the revolution, General Marion gained supporters from Major John James. The Battle of King's Tree took place on August 27, 1780. The city sustained losses, including Indiantown Presbyterian Church being burned to the ground.
The Kingstree Historic District, M.F. Heller House, Colonel John Gotea Pressley House, Scott House, and Thorntree are listed on the National Register of Historic Places.
Williamsburg Presbyterian Church was founded in August 1736. The church consisted of three structures.
