The Mapuche uprising of 1655 (Spanish: alzamiento mapuche de 1655 or levantamiento mapuche de 1655) was a series of coordinated Mapuche attacks against Spanish settlements and forts in colonial Chile. It was the worst military crisis in Chile in decades, and contemporaries even considered the possibility of a civil war among the Spanish. The uprising marks the beginning of a ten-year period of warfare between the Spanish and the Mapuche.
