Arizona State Route 93, abbreviated SR 93, was a state highway in Arizona that existed from 1946 to 1991. The route was co-signed with other highways along nearly all of its route from Kingman to the border at Nogales. SR 93 was the original designation for the highway from Kingman to Wickenburg, which was built in 1946. In 1965, the northern terminus of the state route was moved south to an unnamed desert junction with U.S. Route 89 just north of Wickenburg, and the southern terminus of U.S. Route 93 was moved south to the US 89 junction. The Arizona Highway Department sought U.S. Highway status for SR 93 across the rest of the state, but the proposal was never granted by AASHTO. On December 17, 1984, the SR 93 designation was removed south of the Grand Avenue/Van Buren Street/7th Avenue intersection in Phoenix. The route was completely decommissioned in 1991.

The total length of US 93 in Arizona is 199.38 miles. Between Wickenburg and Interstate 40 (I-40), part of US 93 is designated as the Joshua Forest Scenic Byway. While most of US 93 is a four-lane divided highway, sections of the highway between Wickenburg and I-40 are still narrow two-lane roads, gradually being upgraded to match the rest of the route. As part of a proposal by municipal leaders in Nevada and Arizona, the highway could be replaced by Interstate 11 (I-11).
Below is a list and summary of the former state routes in Arizona, including mileage tables and maps. Between the establishment of Arizona's numbered state highway system in 1927 and the present date, several state routes have been decommissioned. Some state routes were retired as a result of the state relinquishing ownership to local authorities, while others were made extensions of or redesignated as other highways, with some former state routes being upgraded to U.S. Highway or Interstate status.
Interstate business routes are roads connecting a central or commercial district of a city or town with an Interstate bypass. These roads typically follow along local streets often along a former U.S. Route or state highway that had been replaced by an Interstate. Interstate business route reassurance markers are signed as either loops or spurs using a green shield shaped and numbered like the shield of the parent Interstate highway.
