Miss Illinois USA

The  Miss Illinois USA pageant is a competition that selects the representative for the state Illinois in the Miss USA pageant. It is directed by Vanbros and Associates and is previously directed by D&D Productions from 2001 to 2014 before becoming part of Vanbros organization in 2014, headquartered in Shawnee.

Illinois is one of the most successful states in the competition. It is one of only four states to have won four or more Miss USA titles and one of only four states to win two Miss USA titles in consecutive years. All four winners came from the early history of the competition, with their last Miss USA being Karen Morrison, who held the title in 1974. The pageant's most successful years were from 1984 to 1996, when all but two delegates made the cut at Miss USA. That period was followed by many years without a placement.

In 1986, sisters Tricia and Laura Bach won the title consecutively, the first occasion of this in the history of the Miss Universe organization. Later on, in 1994, Kathleen Farrell, sister of Miss Florida USA 1988, won the title, making the state pageant the first to have two sisters compete in Miss USA.

Until 2013, no Illinois delegate had previously competed at Miss Illinois Teen USA but one was previously competed in Miss Illinois, Stacie Juris became the first former Teen titleholder to appear a crossover in Miss USA, the second-to-the last state to do so (Washington would make its first Teen to Miss crossover four years later). The most recent placement was Samantha Elliott placing Top 20 in 2023.

Grace Rodi of Hinsdale was crowned Miss Illinois USA 2024 on May 26, 2024, at Braden Auditorium in Normal. She will represent Illinois at Miss USA 2024.
