Iglesia de San Pedro Apóstol, Catholic parish church in Metapán, El Salvador.

Iglesia de San Pedro Apóstol is a Catholic parish church in the historic centre of Metapán, Santa Ana department, El Salvador. Its Baroque facade rises 28 metres and is organised as a three-tier retablo: the lower tiers carry Ionic columns and niches crowned with triangular pediments, while the upper tier takes a Baroque form ending in a calyx-shaped finial. Four catacombs or vaults lie beneath the floor, only one of them open to visitors.

Construction began in 1736 and finished in 1743, the year Metapán's municipality was founded; the twin towns Santiago Metapán and San Pedro Metapán joined to build it. It is attributed to the alarife Felipe de Porrez under the cura Francisco Javier Estrada. Repairs were reported on 15 January 1862, and on 5 June 1953 the Legislative Assembly declared it a National Monument by decree 1053, ratified by President Oscar Osorio on 11 June.

The church serves as the community's main gathering place for Catholic worship and remains central to the spiritual life of Metapán residents. People come here for weekly masses, baptisms, and celebrations that mark important moments in their lives.

The church is located in Metapán's central plaza, making it easy to find and access on foot. Visitors should be mindful of service times if planning to explore the interior at their own pace.

Beneath the floor lie four catacombs or underground vaults; by 2016 only one was open to visitors. The most widespread explanation is that they served as burial chambers for prominent parishioners who funded the parish, but when they were opened in the 20th century it was found that in the mid-19th century they had been used as common graves.
