Isaac Maliyamungu, (died February 1984) also known as Isaac Lugonzo, was a military officer of the Uganda Army (UA) who served as one of President Idi Amin's most important officials and supporters during the Ugandan military dictatorship of 1971–79. Born in Zaire, Maliyamungu was one of the members of the 1971 coup that brought Amin to power, and was thereafter responsible for brutally suppressing dissidents throughout the country. Rising in the ranks, Maliyamungu amassed great power and earned a feared reputation. He was responsible for the mass murder of civilians and soldiers suspected of being disloyal to Amin.
