State Road 15 (SR 15) is a north–south state road in northern part of the US state of Indiana. Its southern terminus is at U.S. Highway 35 (US 35) and SR 22 near Jonesboro and its northern terminus is the Michigan state line, north of Bristol, where the roadway continues north as M-103. It is a surface highway that mostly passes farm fields but passing through a few cities of Marion, Wabash, Warsaw, and Goshen. Running for 94.835 miles (152.622 km) through the state, SR 15 is maintained by the Indiana Department of Transportation (INDOT).

Dating back to the before the state road system, the corridor that SR 15 takes today was part of the Hoosier Dixie Highway. The first numbered route along the modern SR 15 corridor was SR 27, while SR 15 ran from Indianapolis to near Michigan City. SR 15 was moved to its modern routing in late 1926, running from Marion to Goshen. During the late 1920s, SR 15 was moved onto its modern routing between Milford and New Paris. In 1930 the road was extended from Goshen to Michigan. The route from Wabash to SR 114 was moved to its modern route in the mid-1930s. In late 1940s and early 1950s, SR 15 was rerouted between La Fontaine and Wabash, while the route was extended south from Marion to Jonesboro.
