Arkansas Highway 18 (AR 18) is a designation for two state highways in northeast Arkansas. One segment of 0.93 miles (1.50 km) runs from Highway 69 east of Jacksonport east to Highway 17 in Diaz. A second segment of 93.1 miles (149.8 km) runs from Highway 17 in Diaz east to the Mississippi River.

Highway 18 begins at Highway 69 east of Jacksonport and heads north for 0.93 miles (1.50 km) until it reaches the intersection of Highway 17 in Diaz, where it terminates.

The route begins at Highway 17 in Diaz and runs east, before meeting US 67 (Future I-57) in Newport. Highway 18 continues east to Highway 37 in Grubbs before turning north at Uno to Highway 226 in Cash. The route joins Highway 91 and becomes King's Highway.

Highway 18/Highway 91 run together with US 63 into Jonesboro. Highway 18 breaks and runs as Highland Drive, meeting US 49/Highway 1. Then later, it meets US 78 where it begins concurrency with. After Jonesboro, US 78/Highway 18 meets Highway 158 and Highway 135 in Lake City. The four routes continue east to Black Oak, when US 78/Highway 18 turns north. US 78/Highway 18 briefly runs with Highway 139 in Monette before continuing east. Highway 18B is created in Manila, and US 78/Highway 18 meets Highway 77.

Both routes briefly meets Highway 181 near Dell before turning northeast to Blytheville. US 78/Highway 18 meet Highway 151 and US 61 in downtown Blytheville. The route continues east to cross over I-55 (exit 67) in a frontage road interchange where US 78 departs from the highway to enter I-55. Highway 18 and Highway 312 meet briefly south of the Blytheville Municipal Airport. The route continues east to end at the Mississippi River.
