The Marmion Academy was created in 1933 when the monks of St. Meinrad Abbey combined Jasper Academy with the Fox Valley Catholic High School, which the Augustinians had just returned to the diocese of Rockford. During the Great Depression era it was difficult for students to pay their tuition as well as uniforms, so the monks, in 1935, associated with the JROTC program and changed its name to Marmion Military Academy. At the time, all JROTC uniforms were provided for by the US government. In the 1990s in order to provide more options for its student body and a return to the original spirit of the school, the monks of Marmion Abbey decided to make JROTC an optional program and to reinstitute the original name of the school, Marmion Academy. At one point, there were two campuses: one for residential students and one for day students. The two merged back into the Butterfield Road campus, which had been the residential campus. In early 2002, the school decided to close its residential program and started to expand its student body. In sports, the Cadets have been successful. In 2000, the Marmion swim team captured the school's first state championship, along with a 3rd place in 1998, 2nd in 1999, and 3rd in 2001. Later that decade, the 2010 Marmion Cadets placed 2nd in the state in the 6A State Championship for football and 3rd in the Cross Country Class 2A State Championships. In 2017, the Marmion Cadets baseball team finished 3rd in the 3A State Finals. Just a year later, the Cadets captured their 2nd state championship in school history as the track and field team won the 2018 Class 2A State Championship.
