Highway 302 is a designation for three east–west state highways in the Arkansas Grand Prairie. All three are low traffic rural highways. The first segment was created in 1963, with the other two added ten years later. One segment was part of the Trail of Tears and is preserved as an Arkansas Heritage Trail. All are maintained by the Arkansas Department of Transportation (ArDOT).
