Moluche or Nguluche is a dialect of the Mapuche language Mapudungun that is also the ethnic description of the Mapuche peoples speaking that language. At the beginning of the Conquest of Chile by the Spanish Empire the Moluche lived in what came to be known as Araucanía. The Moluche were called Araucanos ("Araucanians") by the Spanish.
Descendants of the Moluche and the Pehuenche and Huilliche later migrated into Argentina in later centuries mixing with the local tribes. This Araucanization made their language the common spoken language in the region.
