State Route 15 (SR 15) is a north–south and east–west route in northwestern Ohio. Its southern (eastern) terminus is at its interchange with U.S. Route 23/State Route 103 (US 23/SR 103) near Carey, and its northern (western) terminus is at the Michigan state line north of Pioneer, where the route continues in Michigan as M-99. The route is signed east–west from Carey to Bryan, and it is signed north–south from there to the Michigan state line.
SR 15 is an expressway for its southernmost 19 miles (31 km): two miles (3.2 km) where it runs concurrently with Interstate 75 (I-75), three miles (4.8 km) where it runs concurrently with US 68, and the final 14 miles (23 km) as a stand-alone limited-access road until its junction with US 23. The final 17 miles (27 km) are part of a heavily traveled corridor providing the most direct route between Detroit, Toledo, Findlay, Marion and Columbus.

SR 15 was certified in 1923, along the current US 322, which replaced it in 1926.
In 1926 the designation was reapplied to a route from Carey to the Indiana state line. In 1929 it was rerouted to Bryan, replacing parts of SR 9. It replaced the rest of SR 9 in 1931, rerouted along its current route to the Michigan state line.
In 1966, SR 15 was rerouted on an expressway from I-75 in Findlay to US 23 in Carey, its new southern (eastern) terminus. The highway runs a few miles south of its previous routing, which was recertified as SR 568 the same year.
