Arkansas Highway 13 (AR 13) is a designation for three state highways in central Arkansas. One segment of 54.79 miles (88.18 km) runs from US 63/US 79 in Humphrey north to Campground Road east of Beebe. A second segment of 17.76 miles (28.58 km) runs from Highway 367 in McRae north to Highway 385 west of Judsonia. A third segment of 5.91 miles (9.51 km) runs from Highway 367 in Judsonia north to Highway 258 east of Providence.

The southern part of Highway 13 was replaced by Highway 81 during World War II. Then, in 1989, when US 425 was commissioned, it replaced most of Highway 81.

Highway 13 begins at US 63/US 79 in Humphrey and heads north to US 165 in Humnoke. The route continues north to a crossing of both Interstate 40 (I-40) and US 70 in Carlisle before meeting Campground Road east of Beebe, where it terminates.

The route begins in McRae at Highway 367 and runs north across US 64/US 67/US 167 (Future I-57), which are concurrent. Highway 13 is exit 35 on the converged highways. The route crosses Highway 267 before continuing north to Highway 36 (Beebe Capps Expressway) at the western city limit of Searcy before meeting Highway 385 west of Judsonia, where it terminates.

The route begins at Highway 367 near Friendly Acres Park and runs west as Missile Base Road. Highway 13 meets US 64/US 67/US 167 (Future I-57) at a grade-separated interchange north of Judsonia. After this bridging, Highway 13 turns north to intersect Highway 157 before terminating at Highway 258 near the Emmett Miller House east of Providence.

Highway 13 was one of the original 1926 state highways. The route ran about 90 miles (140 km) from U.S. Route 65 south of Pine Bluff to the Louisiana state line, where it continued as Louisiana Highway 139. The section from Highway 38 to US 70 was designated in 1941. In 1945, the original portion of the route was renumbered Highway 81, which this section was replaced by US 425 when it was commissioned in 1989. The route extended north to Beebe and south to Humphrey later. In 1994, the road replaced the two sections of Arkansas Highway 371 from McRae to Highway 267 and from Judsonia to Highway 258 to avoid conflict with the newly designated US 371.
