State Route 1 (SR 1) is a former state highway in Ohio originally planned as a second Ohio Turnpike. Its southern terminus was in Cincinnati, and its northern terminus was in Conneaut at the Pennsylvania state line. The majority of its route is now Interstate 71.

SR 1 was not used for any Ohio highway again until 1961. After planning had been completed for the Ohio Turnpike and construction of the Turnpike was substantially underway, Ohio highway authorities began planning a second Ohio Turnpike extending southwest to northeast across the state. It was planned to run from Cincinnati to Conneaut and connect with an extension built across the panhandle of Pennsylvania to the New York State Thruway. As the highway was being planned, the Federal Aid Highway Act of 1956 was enacted, and the project was converted from a toll road to a free Interstate Highway. It was designated as SR 1, since the Interstate Highway numbering system had not yet been implemented. Portions of the freeway began to be completed and opened in 1959 with the new Interstate Highway funding, and they were later marked as SR 1 (the Interstate Highway numbers did not go up until 1962). Since large gaps existed along the corridor where no freeway had yet been completed, existing two-lane or four-lane highways were designated as Temporary SR 1 in order to complete the route.
