Highway 9 is a designation for two north–south state highways in Arkansas. A southern segment of 51.44 miles (82.78 km) begins at U.S. Route 79 at Eagle Mills and heads north to U.S. Route 67 in Malvern before terminating. The northern segment of 174.17 miles (280.30 km) runs from AR 5 to U.S. Route 63 in Mammoth Spring. The route was created during the 1926 Arkansas state highway numbering, and has seen only minor extensions and realignments since. Pieces of both routes are designated as Arkansas Heritage Trails for use during the Civil War and the Trail of Tears.
