Highway 231 (AR 231, Ark. 231, and Hwy. 231) is a designation for three north–south state highways in northeast Arkansas. All three segments serve rural, agricultural areas in the Arkansas Delta. One segment of 5.79 miles (9.32 km) runs north from U.S. Route 412 (US 412) to Highway 34.^[2] A second route of 3.02 miles (4.86 km) begins at Highway 90 near O'Kean and runs north to Highway 304 at Sharum. A third segment of 6.12 miles (9.85 km) begins at Highway 251 and runs to Highway 93.^[3] All routes are maintained by the Arkansas State Highway and Transportation Department (AHTD).^[1]

The highway begins at U.S. Route 412 (US 412) east of Walnut Ridge near the Cache River and the Green County line. Highway 231 runs north through an agricultural area before turning northwest and intersecting the Union Pacific Railroad line, which parallels Highway 34 through the region. Shortly after this at-grade crossing, Highway 231 terminates at Highway 34.^[2]

Highway 231 begins in the southeast corner of Randolph County near the city of O'Kean at an intersection with Highway 90. The minor connector route runs due north along a section line to Highway 304, where it terminates near the unincorporated community of Sharum. The highway serves an agricultural area near the Black River.^[3]

Highway 231 begins at Highway 251 several miles northwest of Pocahontas near the Missouri state line. Odd-numbered Arkansas state highways are traditionally north–south routes, and as a result, are usually signed north–south even if the actual roadway alignment is east–west. This segment of Highway 231 runs west, passing through the unincorporated community of Hamil, to Highway 93, where it terminates.^[3]
