The 2004 Arizona Wildcats football team represented the University of Arizona during the 2004 NCAA Division I-A football season. They were coached by Mike Stoops in his first season with the Wildcats, after taking over the program after a disastrous 2003 season that led to the firing of former Arizona coach John Mackovic. Arizona finished the season with a record of 3–8 (2–6 against Pac-10 opponents), which was a slight improvement from 2003. A major highlight of the year was an upset victory over rival Arizona State in the finale that showed signs that the program was returning to relevance.
