Highway 81 (AR 81, Ark. 81, and Hwy. 81) is a north–south state highway in Jefferson County, Arkansas. The highway begins at an intersection with US Highway 65 (US 65) and US 425 and runs 2.29 miles (3.69 km) to US 63/US 79. The designation also includes a spur route, Highway 81 Spur, created in 2005. Both highways are maintained by the Arkansas State Highway and Transportation Department (AHTD).

The Highway 81 designation has also been used for a former highway in Arkansas. A route between Arkansas City and Rohwer held the Highway 81 designation between 1926 and 1929. The designation was reused in 1945 to replace Highway 13 between Louisiana and US 65 east of Pine Bluff (present-day US 425).
