Beaufort County (/ˈbjuːfərt/ bew-fərt) is a county located in the U.S. state of South Carolina. As of the 2010 census, its population was 162,233. Its county seat is Beaufort.

Beaufort County is included in the Hilton Head Island-Bluffton-Beaufort, SC Metropolitan Statistical Area.

Beaufort County is one of the South's fastest-growing counties,  primarily because of development south of the Broad River clustered along the U.S. Highway 278 corridor. The northern portions of the county have also grown steadily, due in part to the strong federal military presence around the city of Beaufort.

The two portions of the county are physically connected via the Broad River Bridge, which carries South Carolina Highway 170. Despite the connectivity, often the "north of Broad" and "south of Broad" populations of the county find each other at odds over county-wide issues dealing with growth management
