Marmion Abbey is a Benedictine community of the Swiss-American Congregation in Aurora, Illinois. It was founded in 1933 from St. Meinrad Archabbey in Indiana.^{[citation needed]}

The principal apostolate of the monks has been Marmion Academy, though a variety of work has been undertaken by them throughout the Fox Valley area and beyond, particularly their mission priory in Quetzaltenango, Guatemala, where they operate a minor seminary.^{[citation needed]}

The fifth abbot, John Brahill, retired in 2023. His successor, Joel Rippinger, was elected on August 19 of that year.^[1]
