State Route 129 (SR 129) is an east–west highway in southwest Ohio running from its western terminus at SR 126 and Indiana State Road 252, just east of the Indiana–Ohio state line near Scipio, Ohio. Its eastern terminus is east of Interstate 75 (I-75) at Cox Road in Liberty Township. The route's eastern terminus was historically at SR 747 until 1999 when the route was moved south 1⁄2 mile (0.80 km) to the newly built Butler County Veterans Highway.
