Ladislas Ntaganzwa (born 1962) is a Rwandan war criminal who was involved in the 1994 Rwandan genocide. According to his indictment, Ntaganzwa, as mayor of Nyakizu, a commune of Butare, was instrumental in rallying Hutu Power fervor leading up to the genocide, and as the genocide began, distributed weapons, and directed and participated in killings.
On April 18, 1994, after a visit by interim President Sindikubwabo, during which he had called for the assassination of more Tutsis, Ntaganzwa allegedly ordered and led a massacre of Tutsis who had survived the first attack.
