The Edgefield County Courthouse in Edgefield, South Carolina, is a distinguished example of 19th-century civic architecture and a central landmark in the town’s historic district.​

• Early Courthouses: The site for the courthouse was selected in 1785, with the first structure—a weather-boarded building—constructed between 1787 and 1788. A second brick courthouse was built around 1809. In 1826, renowned architect Robert Mills enhanced this building by adding porticos on both sides. ​
• Current Structure: The present courthouse was completed in 1839, designed by Charles Beck, a protégé of Robert Mills. Although Mills did not directly design this building, it incorporates many of his stylistic elements, making it one of the finest examples of his architectural influence. ​
• 20th-Century Renovations: In the 1930s, architect Elroy G. Smith oversaw significant expansions and modernizations of the courthouse, ensuring its continued functionality while preserving its historical character. ​

The courthouse showcases Greek Revival architectural style, characterized by its symmetrical design and classical elements. It stands as a contributing property within the Edgefield Historic District, which encompasses numerous 19th-century buildings, including homes, churches, and commercial structures. The district was added to the National Register of Historic Places in 1972, highlighting its importance in South Carolina’s architectural and historical heritage. ​
