Highway 3 (AR 3, Ark. 3, Hwy. 3, formerly State Road 3) was a state highway in southern Arkansas. Running predominantly southwest to northeast, its southern terminus was at the Louisiana state line approximately 18 miles (29 km) south of Magnolia, Arkansas. Its northern terminus was at U.S. Highway 64 approximately 3 miles (4.8 km) north of Lehi.

Between Magnolia and Lehi, Highway 3 was replaced in 1935 by US 79, while the segment north of Lehi was replaced by Highway 147; another segment south of Lehi later became Highway 147 and Highway 50 after U.S. 79 was rerouted. Between Magnolia and the Louisiana state line, Highway 3 is now part of Highway 19.
