State Route 317 (SR 317) is a north–south state highway in the central portion of the U.S. state of Ohio. Its southern terminus is at U.S. Route 23 approximately 9 miles (14 km) south of Downtown Columbus and just outside the city limits; its northern terminus is at U.S. Route 62 in Gahanna. The route serves as a partial southeastern outbelt for the Columbus metropolitan area, passing through many commercial districts and light industry areas.

SR 317 was established in the early 1930s. The highway was extended three times, the first in the early 1960s, to US 33. The second time the route was in the early 1970s and it was extended south to Groveport. The final time the route was extended was in the mid-1970s and the route was extended to US 23.
