Loyola University Chicago Quinlan School of Business encompasses the undergraduate, graduate, and executive-level business programs of Loyola University Chicago in downtown Chicago, Illinois, with campuses and partnerships in Rome, Beijing, and Saigon-Ho Chi Minh City. It is Chicago's only Jesuit business school.

Quinlan was founded in 1922 to help working-class employees move from the factory floor to the front office. In 2012, it was named for Michael R. Quinlan, the University's two-time alumnus, who worked his way up from the mailroom to the boardroom of McDonald's as chairman and CEO.
