Aurora Central Catholic High School (ACC) is a Roman Catholic secondary school under the direction of the Diocese of Rockford. ACC began as two separate secondary schools in 1926 and 1962. Madonna Catholic High School, a girls school, and Roncalli High School, a boys school, merged in 1968 to become Aurora Central Catholic. The first campus was located on the east side of Aurora, Illinois, in what is now Cowherd Middle School. The school moved to its current location, on Aurora's west side, in 1995. The 2023 student body was about 450 students.
