The Picunche (a Mapudungun word meaning "North People"), also referred to as picones by the Spanish, were a Mapudungun-speaking people living to the north of the Mapuches or Araucanians (a name given to those Mapuche living between the Itata and Toltén rivers) and south of the Choapa River and the Diaguitas. Until the Conquest of Chile the Itata was the natural limit between the Mapuche, located to the south, and Picunche, to the north. During the Inca attempt to conquer Chile the southern Picunche peoples that successfully resisted them were later known as the Promaucaes.

The Picunche living north of the Promaucaes were called Quillotanes (those living in the Aconcagua River valley north to the Choapa) and Mapochoes (those living in the Maipo River basin) by the Spanish, and were part of the Inca Empire at the time when the first Spaniards arrived in Chile.

Among the peoples the Spanish called the Promaucaes, the people of the Rapel River valley were particularly called by this name by the Spanish. Those of the Mataquito River valley were called the Cures. and Cauquenes by the Spanish) and Cuyo (Huarpe). Few in numbers, disconnected from their ancestral lands and diluted by mestizaje the Picunche and their descendants lost their Indigenous identity.
