Pelantaro or Pelantarú (Spanish: [pelanˈtaɾo]; from Mapudungun: pelontraru, lit. 'Shining Caracara') was one of the vice toquis of Paillamachu, the toqui or military leader of the Mapuche people during the Mapuche uprising in 1598. Pelantaro and his lieutenants Anganamon and Guaiquimilla were credited with the death of the second Spanish Governor of Chile, Martín García Óñez de Loyola, during the Battle of Curalaba on December 21, 1598.
This provoked a general rising of the Mapuche and the other indigenous people associated with them. They succeeded in destroying all of the Spanish settlements south of the Bio-bio River and some to the north of it (Santa Cruz de Oñez and San Bartolomé de Chillán in 1599). After this actions, the following Governor, Alonso de Ribera, fixed a border and took the suggestions of the Jesuit Luis de Valdivia to fight a defensive war.
