State Route 26 is a 67-mile-long (108 km) north–south route in south eastern Ohio spanning from SR 7 in Marietta to SR 148 between Jerusalem and Bethesda. SR 26 also passes through Graysville and Woodsfield. Where the state route designation ends in Wayne Township, the road continues north as Belmont County Road 26 where it connects to the Barkcamp State Park and the National Road. Much of the route parallels the Little Muskingum River and travels through the heart of Wayne National Forest's Marietta Unit.
