State Route 103 (SR 103) is a 77.07-mile (124.03 km) state route that runs between Bluffton and Willard in the US state of Ohio. Most of the route is a rural two-lane highway and passes through both farmland and residential properties. In Bluffton the route has two interchanges with Interstate 75 (I–75).

The highway was first signed in 1923 on much the same alignment as today. In both 1935 and 1938 the route was extended east. The entire route was paved by 1939. Some of the highway replaced U.S. Route 25 (US 25), in 1964. SR 103 replaced the SR 194 and SR 298 designation of the highway from Chatfield to Willard, in 1969.
