State Road 37 (SR 37) is a major route in the U.S. state of Indiana, running as a four-lane divided highway for a majority of its course in Southern and Central Indiana.
At one time, the route ran from the southwest corner of the state to the northeast corner. In the pre-Interstate Highway era, SR 37 was the most direct route between Fort Wayne and Indianapolis. Interstate 69 (I-69) has supplanted it as a through route, and SR 37 now consists of three disconnected segments, with the segment through Indianapolis being replaced entirely by I-69 in 2024. The longer segment starts at Tell City on the Ohio River and ends in Bloomington in south central Indiana. Another shorter segment resumes off I-69 and runs northeast to SR 9 in Marion. The other segment in northeastern Indiana runs from I-469 near Fort Wayne to the Ohio state line.
