An attempted coup d'etat in Burundi took place between 18–19 October 1965, when a group of ethnic Hutu officers from the Burundian military and gendarmerie attempted to overthrow Burundi's government. The rebels were frustrated with Burundi's monarch, Mwami Mwambutsa IV, who had repeatedly attempted to cement his control over the government and bypassed parliamentary norms despite Hutu electoral gains. Although the prime minister was shot and wounded, the coup failed due to the intervention of a contingent of troops led by Captain Michel Micombero.
