State Highway 79 or SH 79 is a state highway in the U.S. state of Texas that runs 96 miles (154 km) from the Oklahoma border near Wichita Falls to Throckmorton. It was originally designated in 1926 along its current route, except for the unfinished portion from Olney to Elbert. This section was completed by 1938. The route was previously proposed as the northern sections of SH 22 and SH 23. The intersection of Hwy 79 and Hwy 25 was the location for the filming of movie The Last Picture Show in 1971.
