Juma Ali Oka Rokoni, commonly referred to as Juma Butabika, (died April 1979) was a Ugandan military officer who served as Uganda Army (UA) top commander during the dictatorship of Idi Amin. Despite being notorious for his erratic behavior and abuse of power, he was highly influential, held important army commands, and served as long-time chairman of the Ugandan Military Tribunal, a military court used by Amin to try and eliminate political dissidents and rivals. By commanding an unauthorized attack on Tanzania in October 1978, Butabika was responsible for the outbreak of the Uganda–Tanzania War which ultimately resulted in his death in combat, probably during or shortly before the Fall of Kampala.
