The Iowa–Iowa State football rivalry is an American college footballrivalry between the Iowa Hawkeyes and the Iowa State Cyclones. 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 GovernorRobert D. Ray in 1977. That game was the first meeting between the two since 1934.
A new trophy, donated by the Iowa Corn Growers Association, was introduced to the public during the Iowa State Fair on August 19, 2011. A sculpture atop the new trophy depicted a farm family with small children huddled about a bushel basket of corn. Dean Taylor, president of the Association, called it "a work of art that represents Iowans and their hard work." Within hours of its presentation, however, the new trophy was widely ridiculed in newspaper columns and internet postings by the public. Iowa GovernorTerry Branstad publicly provided negative feedback, as did retired Iowa football coach Hayden Fry, who said, "The farmer, family and corn is all wonderful, but I don't really get the relationship to a football game."
On August 23, 2011, Iowa Corn Growers Association CEO Craig Floss announced that the new Cy-Hawk Trophy would be changed as a result of the negative public reaction. Selection of the new trophy would involve public input. A temporary trophy was used for 2011. 
With fan input, the newly, redesigned trophy was unveiled at the conclusion of the 2012 game won by Iowa State featuring mascots of the two universities, a raised football, and corn making up the background.
The two schools played each other 24 times between 1894 and 1934, before the Cy-Hawk Trophy was established in 1977. The series halted after 1934 after then University of Iowa Athletic Director and head football coach Ossie Solem would not return calls to reschedule the rivalry.
