The Iglesia de las Agustinas is a Catholic church, located in downtown Santiago, Chile.

[1] It was built on a city block bounded by the present day streets of Augustinas on the north, Ahumada on the east, Bandera on the west and the Moneda on the south.

[2] In 1850, the site was newly divided into two city blocks to join the discontinuous segments of Moneda street.

Land lots were sold over the following years, leaving the Augustine sisters congregation as the owner only of the southern city block.

The Edificio Ex Hotel Mundial, the Santiago Stock Exchange Building and the Club de la Unión were built on this site.
