Rock-A-Thon is an extensive philanthropic effort coordinated by the men of Alpha Epsilon Pi at the University of Missouri in Columbia and benefiting the American Cancer Society. The event has remained a Columbia staple since its formation in 1969.

In 2025, Rock-A-Thon raised over $212,000 to remain the largest single-chapter fraternity and sorority philanthropy in North America. AEPi Rock-A-Thon’s goal is to exceed that record in 2027.

The event itself is hosted on a stage at the northwest corner of 9th and Broadway in downtown Columbia, Missouri. One brother from the fraternity is elected to rock on a rocking chair for 63 straight hours while the remainder of the brotherhood and additional volunteers solicit donations through canning across the state of Missouri.
