John Mugabi (born March 4, 1960) is a Ugandan former professional boxer who competed from 1980 to 1991, and 1996 to 1999. He held the WBC super-welterweight title from 1989 to 1990, and challenged twice for world titles at middleweight, including the undisputed championship.

As an amateur, Mugabi won a silver medal in the welterweight division at the 1980 Summer Olympics, and was the only medallist for Uganda at the event.
