State Route 621 (SR 621) is a north–south state highway in the central part of the U.S. state of Ohio. The southern terminus of SR 621 is at U.S. Route 36 (US 36) approximately two and a half miles (4.0 km) northeast of Coshocton, and its northern terminus is adjacent to the North Appalachian Experimental Watershed Station, just north of its intersection with White Eyes Township Road 188, about 5 miles (8.0 km) northwest of the hamlet of Fresno. Continuing north after SR 621 ends is County Road 190 (CR 190).
Established in the early 1940s, SR 621 is a two-lane spur route whose primary purpose is to provide access to the North Appalachian Experimental Watershed Station from the state highway network. The entirety of the route exists within Coshocton County.
