State Route 646 (SR 646) is a 28.78-mile-long (46.32 km) state highway in Harrison and Jefferson Counties in eastern Ohio. The route runs from US 250 in , northwest of Cadiz, to SR 43 in Island Creek Township, just outside Wintersville.
SR 646 begins at a stop-controlled intersection with US 250 in Stock Township, Harrison County; about 8 miles (13 km) northwest of Cadiz. The intersection is on the shoreline of Tappan Lake. The state route heads northeast towards Scio through a valley formed by a small creek. Once it reaches Scio, the route makes numerous turns, has a grade crossing with an Ohio Central Railroad and the Conotton Creek Trail, and shares a brief concurrency with SR 151. Upon exiting the village, SR 646 travels in a more easterly direction. The route heads through the hills of Appalachia passing through the villages of New Rumley, the birthplace of General George Armstrong Custer, and Germano. In Germano, SR 646 runs concurrent with SR 9 for about 0.6 miles (0.97 km). East of Germano, the road intersects County Road 51 (formerly a grade-separated interchange) and an Ohi-Rail Corporation rail line.
