Sumter County Courthouse, County courthouse in Sumter, South Carolina.

The Sumter County Courthouse is a Beaux-Arts courthouse at 141 North Main Street in Sumter, South Carolina, built in 1907 to an I-shaped plan. Darlington native William Augustus Edwards, who designed eight other South Carolina courthouses, was its architect. The building was enlarged and remodeled in the early 1960s and added to the National Register of Historic Places on June 16, 2004.

The Sumter County Courthouse was built in 1907 to designs by Darlington native William Augustus Edwards, who drew plans for eight other South Carolina courthouses and academic buildings at twelve institutions across Florida, Georgia and South Carolina. It was enlarged and remodeled in the early 1960s and added to the National Register of Historic Places on June 16, 2004.

The courthouse stands within the Sumter Historic District, and its 1907 construction replaced an earlier county courthouse on the same Main Street site. Visitors can note the building's placement at 141 North Main Street, a downtown address it has held since its Beaux-Arts design by William Augustus Edwards was completed.

The courthouse stands at 141 North Main Street in downtown Sumter, within the Sumter Historic District, so nearby historic buildings can be visited on the same walk. It is a working county courthouse: courtrooms and records offices are in active use, so visitors should expect security checks and restricted areas rather than open sightseeing.

The courthouse was built in an I-shape in 1907 and enlarged and remodeled in the early 1960s, so its plan mixes the original Beaux-Arts design with later additions. It was added to the National Register of Historic Places on June 16, 2004, and stands within the Sumter Historic District.
