State Highway 137 or SH 137 is a Texas state highway that runs from Brownfield to near Ozona in west Texas. This route was designated by 1939 on a route from Brownfield south through Midland and Rankin, ending west of Sheffield. By 1942, everything south of Lamesa was either cancelled, transferred to FM 9, or transferred to SH 51. It was exnteded south to Stanton in 1943, replacing State Highway 303. In 1984, the route was extended 109 miles (175 km) south to its current southern terminus, when it replaced all or portions of RM 33, RM 865, and RM 1800.

SH 137 was previously designed by 1933 along a different west Texas route between Lubbock and McCamey. The portion from Lubbock to Brownfield, which was designated as SH 53, was renumbered as SH 137. By 1936, the route south of Brownfield had become SH 51. By 1939, this route had been reassigned to U.S. Highway 62.
