U.S. Route 95 (US 95) is a major U.S. Highway in the American state of Arizona. Starting at the Mexican border in San Luis, US 95 acts as the main highway north through Gadsden, Somerton and Yuma before arriving in Quartzsite. Between Quartzsite and the California border on the Colorado River in Ehrenberg, US 95 runs entirely concurrent with I-10. Part of US 95 between San Luis and Yuma is maintained by local governments instead of the Arizona Department of Transportation, which maintains the remainder of the route.
US 95 is one of Arizona's younger U.S. Highways, having been established in the state on June 27, 1960. In earlier years, the Arizona section of US 95 was a southern extension of Arizona State Route 95. The route between Quartzsite and San Luis was also the first segment of SR 95 to be commissioned by the Arizona State Highway Department. US 95 used to have major junctions with US 80 in Yuma and US 60/US 70 in Quartzsite, until all three routes were removed from southwestern Arizona between 1969 and 1982.
