Fort Mill is a town in York County in the U.S. state of South Carolina. It is a suburb of Charlotte, North Carolina.

The town of Fort Mill was established in 1873, getting its name from its location between two points, the first, a fort constructed by British in colonial times to protect the Catawba Indians from marauding tribes to the north, and the second point of Webb's Mill.
The Catawba Indians made their home in present-day Fort Mill for many years. Scots-Irish settlers began arriving in the 1750s and 1760s and a small settlement soon developed. Fort Mill grew rapidly in the late 19th century as textile mills were established. After many textile mill shut-downs the town continued to grow rapidly and became a major suburb of Charlotte.
