State Route 37 (SR 37) is a 0.768-mile-long (1.236 km) state highway in Dale County in the southeastern part of the U.S. state of Alabama. The southern terminus of the highway is at an intersection with US 84/SR 134 at Daleville and leads to the Tank Hill Gate of Fort Rucker, where the highway ends. SR 37 is routed along a two-lane undivided highway for its brief length.
The current SR 37 is the second incarnation of the route. In 1940, the original route was designated, heading from near Marvyn to near Oxford. In 1954, the section of the highway from Opelika northwards was redesignated as US 431. In 1960, SR 37 was extended southward, from Marvyn to Hurtsboro. That highway was replaced in 1995 when SR 51 was extended northward from Hurtsboro to what was then the northern terminus of SR 37 at its interchange with Interstate 85 (I-85). The present SR 37 was designated along its current route in 1995.
