Highway 103 (AR 103, Ark. 103, and Hwy. 103) is a designation for two north–south state highways in Arkansas. One segment begins in Clarksville in the Arkansas River Valley and runs north to the Ozark National Forest. A second route runs through a sparsely populated segment of the Ozark Mountains between the Buffalo National River and Highway 21 near the Missouri state line.

The northern segment was created in 1928 and was designated as Arkansas Highway 21E (AR 21E) in the 1950s. Upon restoration as AR 103, the route saw extensions in 1957, 1960, and 1973. The second segment began as AR 123 in 1926 but was renumbered to AR 103 in a 1937 swap. This route was extended in the 1940s, 1963, and 1965. Both routes are maintained by the Arkansas Department of Transportation (ArDOT).
