Arizona Stadium is an outdoor college football stadium in Tucson, Arizona. On the campus of the University of Arizona, it is the home field of the Arizona Wildcats of the Pacific-12 Conference.

Originally constructed in 1928 to hold 7,000 spectators, the stadium's seating capacity has been expanded numerous times since. In 2009, the university announced major expansion plans for the facility, and as of 2012, the stadium had a total capacity of 51,811.

The football field runs in the traditional north–south configuration and the new artificial Field Turf sits at an elevation of 2,430 feet (740 m) above sea level. The ZonaZoo student section takes up 9,000 seats on lower east sideline, making it one of the larger student sections in the Pac-12 Conference. The west side bleachers are generally reserved for season ticket holders and the visiting team gets a section oin the southwest corner.

The facility also includes two dormitories, Pinal and Navajo, in the south stands, and Sierra Hall, which is home to offices for the music and residence life departments, located under the east stands. The Steward Observatory Mirror Lab, a mirror fabrication facility for large telescopes, sits under the east wing. There are also offices located under the west side of the stadium, including part of the Tree Ring Lab.
