Basilica of Nuestra Señora de la Merced, Catholic basilica in historic Lima, Peru.

The Basilica of Nuestra Señora de la Merced is a church in central Lima with a Churrigueresque facade of grey and pink granite from Panama, carved in three sections with Solomonic columns. The central niche holds the Virgin of Mercy, flanked by statues in niches, and a broken pediment above. Its single tower was begun in 1539 and lowered after the 1687 earthquake.

The church was established in 1535 by Mercedarian missionaries and required major rebuilding after severe earthquakes in 1687 and 1746. Significant restoration work took place in 1860 to reinforce the structure and restore its appearance.

The image of the Virgin of Mercy was invoked as the city's protector from 1615, named perpetual Patroness of the Fields of Lima by the civil council in 1730, and patroness of Peru's armed forces by the Constituent Congress in 1823. She was canonically crowned on 24 September 1921 under President Augusto Leguía. Each 24 September she is carried in procession on a silver litter by cadets of the Peruvian armed forces.

The church stands at Jirón de la Unión 621, at the corner of block 6 and the first block of Jirón Antonio Miró Quesada (Calle Jesús Nazareno). The single tower was lowered after the 1687 earthquake, so it rises less than originally planned. Inside, a monumental staircase links the main cloister with the cloister of Los Doctores beneath a half-orange dome.

The sacristy keeps the Cross of the Conquest brought by the Mercedarians. In the library, alongside incunabula and old religious books, stands the chair used by Father Pedro Urraca, kept as a relic. Urraca, born in Jadraque in 1583, is buried at the foot of the altar of the Santo Cristo del Auxilio.
