The Johnson County Courthouse is located at 215 W. Main Street in downtown Clarksville, the county seat of Johnson County, Arkansas. It is a three-story masonry structure, built out of brick and rusticated concrete blocks. It has a Classical Revival facade, with a seven-bay projecting section. Windows and entrances on the ground floor are set in round-arch openings, while the upper-level windows are rectangular sash, set in bays articulated by pilasters. It was built in 1934 with funding support from the Federal Emergency Administration, and is the county's third courthouse.
