This page lists the Barbershop Harmony Society's international quartet champions by the year in which they won. Quartets can only win once, though up to two members may appear together in another quartet and compete again. In this manner individual singers may win multiple gold medals. Several men have won two or three gold medals, and one man, Joe Connelly, has won four. Connelly sang with Interstate Rivals, Keepsake, PLATINUM, and Old School. Connelly was the first to achieve both the 3- and 4-time International Quartet Champion milestone, and Tony DeRosa is the only to achieve 3 wins in multiple voice parts.
