The Arizona Sun Corridor, shortened Sun Corridor, is a megaregion, or megapolitan area, in the southern area of the U.S. state of Arizona. The Sun Corridor is equivalent to Indiana in both size and population. It is one of the fastest growing conurbations in the country and is speculated to double its population by 2040. The largest metropolitan areas are the Phoenix metropolitan area - Valley of the Sun - and the Tucson metropolitan area. The regions' populace is nestled in the valley of a desert environment. Similar to Southern California, the urban area extends into Mexico, reaching the communities of Nogales and Agua Prieta.

Its population is composed of a total of five metropolitan areas: Phoenix, Tucson, Prescott, Sierra Vista-Douglas and Nogales. Out of these, two are metropolitan areas with over 1,000,000 residents: the Phoenix metropolitan area with 4,192,887 residents and the Tucson metropolitan area with 1,020,200 residents. The Arizona Sun Corridor is made up of all of Maricopa, Pinal and Pima counties, along with parts of Yavapai, Santa Cruz and Cochise counties. It is home to over 86 percent of Arizona's population.
