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.
