State Highway 13 (SH 13) was a state highway in the U.S. state of Texas that ran from Amarillo due west to the New Mexico border near Glenrio, Texas.
SH 13 was one of the original 26 state highways proposed in 1917, overlaid on top of the Ozark Trail. From 1917 the routing mostly followed present-day United States Highway 60 from Farwell through Amarillo to Pampa. From there, the highway turned east on present-day SH 152 to the border near Wheeler.
In 1919, SH 13 was completely reassigned to a small segment traveling due east from New Mexico through Amarillo, Hedley, and Wellington to the Oklahoma border. on the route that would later be U.S. Highway 66
In 1926, US 66 was overlaid on the entire SH 13 route west of Amarillo; the routes were marked concurrently. Also in that year, the routing had been pulled back to its Amarillo-Endee segment, while the road east of Amarillo was renumbered as SH 52 (now SH 203). By 1939, SH 13 was canceled, and has never been reassigned.
SH 13A was a spur designated in 1922 from Amarillo east to the Oklahoma state line. By 1926, this route was renumbered as SH 75.
