city, Maricopa county, south-central Arizona, U.S. The name is Spanish for “tabletop” or “tableland.” A southeastern suburb of Phoenix, the site was settled and founded in 1878 by Mormons who used ancient Hohokam (Hohokam culture) canals for irrigation. Laid out on a grid plan with 130-foot- (40-metre-) wide streets, the community became the focus of an agricultural and fruit-growing region, developed from a Salt River reclamation project. It experienced rapid growth after World War II; and its basic farm economy diversified to include manufacturing, tourism, and retail trade. It is the site of a Mormon Temple (1927), Mesa Community College (1965), and the University of Arizona's Agricultural Experimental Station. Salt River Pima-Maricopa Indian Community is across the river to the north. The Chicago Cubs have their spring training camp there. In 2007 commercial air service began at the Phoenix-Mesa Gateway Airport (previously known as the Williams Gateway Airport)—on the site of the former Williams Air Force Base—providing the Phoenix area with its second commercial airport. Inc. town, 1883; city, 1930. Pop. (2000) 396,375; (2006 est.) 447,541.
