Arizona State Sun Devils

The Arizona State Sun Devils are the athletic teams that represent Arizona State University. ASU has nine men's and eleven women's varsity teams competing at the National Collegiate Athletic Association (NCAA) Division I level as a member of the Big 12 Conference. The mascot was adopted in 1946; earlier nicknames were the Normals and later, the Bulldogs. The Sun Devil mascot, Sparky, was designed by Bert Anthony, a former Disney illustrator. ASU's chief rival is the University of Arizona Wildcats, and both universities' athletics departments compete against each other in the Territorial Cup Series.

On August 4, 2023, Arizona State accepted an invite to join the Big 12 Conference, effective August 2, 2024.

Arizona State University sponsors teams in 11 men's and 15 women's NCAA sanctioned sports, following the 2015 elevation of the men's ice hockey club team to varsity status. In the fall of 2015, Arizona State announced the addition of women's triathlon and women's lacrosse. Triathlon began competition in the fall of 2016, with lacrosse starting competition in the spring of 2018. In spring 2016, ASU announced the reinstatement of men's tennis, which had been dropped after the 2007–08 school year.

After the 2006 season, Dirk Koetter was fired after six seasons, and on December 6, 2006, athletic director Lisa Love hired Dennis Erickson to become the head coach at ASU. Erickson, in his first year as coach of the Arizona State Sun Devils, led the team to 10 wins, a share of the Pac-10 title with USC, and the Holiday Bowl against the University of Texas Longhorns. Erickson was fired on November 28, 2011, after five seasons with the Sun Devils. He was replaced by coach Todd Graham on December 14, 2011. Love was fired from her position as vice president for University Athletics and athletics director on March 28, 2012, and was immediately replaced by Steve Patterson. The athletic director from 2014-2023 was Ray Anderson, who selected former NFL player and coach Herm Edwards to replace Graham as Arizona State's head coach in 2018.
