Lautaro (Mapudungun: Lef-Traru "swift Southern Caracara") was the young Mapudungun ("Mapuche") military commander in the four year Arauco War (Araucanian War) in Chile. His people undertook to expel the Spanish colonizers. The army under Lautaro's command inflicted crushing defeats and huge death tolls on Spanish forces despite having far inferior weaponry. He was close to final victory when he was killed in battle at around 23 years of age.

Lautaro was the son of a Mapuche lonko (a chief who holds office during peacetime). He is thought to have been born in 1534. In 1546, he was captured by some Spanish colonizers. He became the personal servant of Don Pedro de Valdivia, Spanish conqueror of Chile and now its Captain General. Lautaro learned the military ways and skills of the Spaniards' army by observation. He was witness to atrocities committed by the Spanish on captive Mapuche warriors.

According to the Chilean novelist Isabel Allende in her historical novel, Inés del Alma Mía, the boy Lautaro had deliberately allowed himself to be captured by the Spanish in order to learn their secrets, and made no attempt to escape until he felt he had learned enough. In any case, he fled twice, in 1550 and for good in 1552. In 1553 (the year Lautaro turned 19), the Mapuches convened to decide how to respond to the Spanish invasion. The convention decided upon war. The toqui Caupolicán chose Lautaro as vice toqui because he had served as a page in the Spanish cavalry, and thereby possessed knowledge of how to defeat the mounted conquistadors. Lautaro introduced use of horses to the Mapuche^{[citation needed]} and designed better combat tactics. He organized a large, cohesive army—a military formation unfamiliar to the Mapuche.
