The 1st Congressional District of South Carolina is a coastal congressional district in South Carolina, represented by Republican Mark Sanford since his election in 2013. The district has historically been based in Charleston. It has included Myrtle Beach, which became a major tourist destination in the late 19th century, as well as other coastal areas that have attracted retirees and seasonal visitors. From 2003 to 2013, the district boundaries extended from Seabrook Island in the south to the North Carolina border and included parts of Charleston, Dorchester, Berkeley and Georgetown counties and all of Horry County to the North Carolina line.
