State Highway 337 (SH 337) is a 21.13NaN3 state highway in the U.S. state of Texas. The highway begins at a junction with US 180 in Mineral Wells, then heads northwest, ending at a junction with SH 16 near Possum Kingdom Lake.
SH 337 was originally designated on December 3, 1940 as a route from SH 78 north of Bailey to SH 34. That route was transferred to FM 68 on August 1, 1942. It was then not designated, but signed on March 30, 1955 over FM 1077 from Plains to the New Mexico state line to match New Mexico Highway 337. On September 26, 1963, this route was transferred to US 82, along with New Mexico Highway 337.
SH 337 was again designated on August 12, 1963 to serve as a route between SH 16 and Mineral Wells.
