The Iowa–Iowa State football rivalry is an American college football rivalry game between the Iowa State Cyclones and Iowa Hawkeyes. Sometimes referred to as ¡El Assico! (a play on El Clásico, the famous Barcelona-Real Madrid soccer rivalry) by commentators and fans of both teams due to frequent low scores and games of dubious quality, the Cy–Hawk Trophy is awarded to the winner of the game.
Conceived and created as a traveling trophy by the Greater Des Moines Athletic Club in 1976, the trophy was first presented to the winner by Iowa Governor Robert D. Ray in 1977. That game was the first meeting between the two since 1934. In the entire history of the rivalry, the game has never been contested anywhere beside Iowa City or Ames and alternates between the two respective campuses. Games in odd-numbered years are played in Ames at Iowa State University, and even-numbered years in Iowa City at the University of Iowa.
