Apiaguaiki Tumpa (c. 1863 – 29 March 1892) was a messianic leader of the Eastern Bolivian Guarani (Chiriguanos) people of Bolivia. He is regarded by many Guarani as a national hero, known for his struggle to defend his peoples' land and liberty from the encroaching Bolivian government, cattle ranchers, and missionaries. He was executed after his defeat and the failure of his revolt. His death is commemorated annually by many Guarani, and a Guaraní language university in the community of Kuruyuki, Bolivia is named after him.
