The school rivalry between Ateneo de Manila University and De La Salle University began when both educational institutions participated in the National Collegiate Athletic Association of the Philippines (NCAA) and has carried over to the University Athletic Association of the Philippines (UAAP) where both universities compete in currently. Before UAAP Season 84, the Ateneo men's varsity team was known as the Ateneo Blue Eagles, the women's varsity team as the Ateneo Lady Eagles, and the high school team as the Ateneo Blue Eaglets. In May 2022, Ateneo de Manila University decided to unify student-athletes and varsity teams under the "Blue Eagles" moniker, regardless of sport, gender, or age group.
