# Iowa Corn Cy-Hawk Series

The Iowa Corn Cy-Hawk Series is an annual athletic competition between Iowa State University and the University of Iowa. On April 12, 2011, it was announced that the competition would be sponsored by the Iowa Corn Promotion Board and the Iowa Corn Growers Association. From 2004 to 2011, it was sponsored by Hy-Vee and called the Hy-Vee Cy-Hawk Series. The competition includes all head-to-head regular season competitions between the two archrival universities in all shared sports. Each team has won the series 9 times, after Iowa won the latest title 2023-2024.

## Competition format

Each regular-season game, match, or meet between the Iowa State Cyclones and the Iowa Hawkeyes is counted toward the series championship. The winning team in each sport earns two points for their university (except for football, which is worth three points). In the event that a contest ends in a tie, the points are split. For academics, each school earns a single point if the graduation rate for student athletes exceeds the overall student body rate. The university with the most overall points at the end of the academic year is awarded the Iowa Corn Cy-Hawk Series Trophy (not to be confused with the Cy-Hawk Trophy, which is awarded to the winner of the schools' annual football game). If both schools tie on points at the end of the academic year (as in 2015–16), the school that won the trophy the previous year keeps the series trophy.

## History

The Cy-Hawk Series Trophy originated in 2004. The series is currently tied, with each school owning nine titles. The two schools tied the series in 2015–16. Due to the COVID pandemic, the Cy-Hawk Series was paused in 2020–2021.
