The Arizona–Arizona State football rivalry (also known as the Duel in the Desert) is a college football rivalry between the University of Arizona Wildcats (UA) and the Arizona State University Sun Devils (ASU).
One of the longest football rivalries, the winner receives the Territorial Cup, created 126 years ago for the 1899 champion between schools in Arizona and which the NCAA has certified as the oldest rivalry trophy in college football. Although the Territorial Cup did not change hands as a regular part of the competition until 2001, the rivalry between the two schools continued after 1899, a semi-regular event until becoming an annual event, uninterrupted, from 1946 onwards. In the entire history of the rivalry, the game has never been contested anywhere beside Tempe or Tucson, and alternates between the two respective campuses. Games in odd-numbered years are played in Tempe at ASU, and even-numbered years in Tucson at UA. It is part of the wider Arizona–Arizona State rivalry, which crosses 20 varsity intercollegiate sports. It is also the biggest and most anticipated football game in the state of Arizona each year.
