The Abbeville County Courthouse, built in 1908, is an historic courthouse located in the east corner of Court Square, in the city of Abbeville in Abbeville County, South Carolina. It was designed in the Beaux Arts style by Darlington native William Augustus Edwards who designed several other South Carolina courthouses as well as academic buildings at 12 institutions in Florida, Georgia and South Carolina. An arcade connects it to the adjoining Abbeville Opera House and Municipal Center, which Edwards also designed. In 1964, the courthouse was renovated by Lyles, Bissett, Carlisle, and Wolff of Columbia. On October 30, 1981, it was added to the National Register of Historic Places.
