The Iglesia Nuestra Señora de Las Mercedes is a Catholic church located in Papudo, Valparaíso Region, Chile.

[1] Papudo was initially used as a port and began its development as a resort beach after the opening of a railroad to the town in the early 20th century.

[2] Its architect was Alberto Cruz Montt, who also designed the building housing the Central Bank of Chile and the Club de la Unión.

The church, which faces the beach of Papudo, has a Latin Cross plan with single nave, and is built in the Spanish Colonial Revival style with Baroque details on its front facade.

[3] The walls of the transept and the nave are reinforced by buttresses, which are separated by windows that are protected by wrought-iron grilles.
