State Route 18 (SR-18) is a state highway in southern Utah, running for 51.005 miles (82.085 km) in Washington and Iron Counties from St. George to Beryl Junction. It forms part of the Legacy Loop Highway from St. George to Parowan. The highway closely follows the route of the Old Spanish Trail through Dixie National Forest.
SR-18 begins at Convention Center/Sunland Drive just south of the Bluff Street interchange with I-15 in St. George as an urban arterial and heads north through the west side of downtown St. George. It continues north through Snow Canyon State Park and continues northwest through Wide Canyon to Dammeron Valley and past Veyo Volcano. It then turns north into Veyo, running through the center of the town.
SR-18 leaves Veyo heading northeast to Central, then continues north and northwest through mountainous terrain in the Dixie National Forest past the Mountain Meadows Massacre site and continues into Enterprise. It turns northeast in eastern Enterprise, then turns north through farmland outside of the town to Beryl Junction, where it ends at an intersection with SR-56.
