The Benton County National Bank is a historic bank building at 123 West Central Street in Bentonville, Arkansas. It is an elegant Classical Revival structure, designed by the regional architect Albert O. Clark and completed in 1906. It has a distinctive Roman-style temple front with three tall round-arch openings, which is sheltered by a projecting gable-pedimented Greek temple front supported by four marble columns with modified Corinthian capitals. A parapet above the Roman front obscures a dome at the center of the building.
