Mesa (/ˈmsə/ MAY-sə) is a city in Maricopa County, Arizona, United States. The population was 504,258 at the 2020 census. It is the third-most populous city in Arizona, after Phoenix and Tucson, the 37th-most populous city in the U.S., and the most populous city that is not a county seat (except for independent cities Washington, D.C. and Baltimore which are not part of any county). It is the most populous city in the East Valley of the Phoenix metropolitan area. It borders Tempe on the west, the Salt River Pima–Maricopa Indian Community on the north, Chandler and Gilbert on the south along with Queen Creek, and Apache Junction on the east.

At least ten colleges and universities are located in Mesa, as is the Mesa Arizona Temple, one of the first LDS temples constructed outside of Utah. The city is home to the largest relief airport in the Phoenix area, Phoenix–Mesa Gateway Airport, located in the southeastern corner of the city.
