Highway 312 (AR 312, Ark. 312, and Hwy. 312) is a designation for three east–west state highways in northern Mississippi County, Arkansas. Two highways are rural, two-lane highways connecting agricultural areas around Blytheville. A third route runs in Blytheville as a city street. The highways were established during a ten-year period, beginning in 1963, and have remained unchanged since establishment. All routes are maintained by the Arkansas Department of Transportation (ArDOT).
