Retiro is a town and commune in Chile, located in Linares Province, in the seventh region of Maule.

Retiro was, therefore, visited frequently by well-known politicians and statesmen of the time, and in general by those that contributed to the decision-making process in the country affairs.

In the area of Copihue (in the southern border of the commune, next to the Pan-American Highway or Ruta 5 Sur), lies the larger poplar wood of the country.

As a commune, Retiro is a third-level administrative division of Chile administered by a municipal council, headed by an alcalde who is directly elected every four years.
