State Route 31 (SR 31) is a 32.12-mile-long (51.69 km) Ohio State Route that runs between Marysville and Kenton in the US state of Ohio. The southern terminus of SR 31 is at an intersection with SR 38 in downtown Marysville and the northern terminus is at an intersection with U.S. Route 68 (US 68), in downtown Kenton. None of the highway is listed on the National Highway System. Most of the route is a rural two-lane highway and passes through both farmland and residential properties.

The highway was first signed in 1926 on much of the same alignment as today. SR 31 replaced the SR 21 designation of the highway which dated back to 1923; SR 21 ran between Pomeroy and Findlay. Some of the route became US 68 in 1933, with another section becoming US 33 in 1938. The southern terminus was relocated to Columbus in the late 1930s and in the early 1940s the southern terminus was moved to Marysville. The northern terminus was moved to Kenton in the early 1950s.
