Dillon County is a county located in the U.S. state of South Carolina. As of the 2010 census, the county's population was 32,062. The county seat is Dillon. Founded in 1910 from a portion of Marion County, both Dillon County and the city of Dillon were named for prosperous local citizen James W. Dillon (1826-1913), an Irishman who settled there and led a campaign to bring the railroad into the community. The result of this effort was the construction of the Wilson Short Cut Railroad, which later became part of the Atlantic Coast Line Railroad, and brought greater prosperity to the area by directly linking Dillon County to the national network of railroads.

Although Dillon County is past its centennial, it's one of the youngest counties in South Carolina, and you will find that much of your genealogical research will be conducted in the records of Marion County (1785-1909) and in the records held at the South Carolina Department of Archives and History in Columbia, SC (pre-1785).

The Dillon County Clerk of Court has civil court records, deeds, real estate and mortgages from 1910.

From 1769 through 1798, the area now known as Dillon County was included in Georgetown District, one of the original South Carolina judicial districts created in 1769. From 1798 through 1909, Dillon County was part of Marion County. In December 1909, residents voted to split from Marion, and Dillon County was officially created in 1910
