The Santa Monica Parish Church, commonly known as the Sarrat Church, is a Roman Catholic parish church in Barangay San Leandro, Poblacion, Sarrat, Ilocos Norte, Philippines. It was built in 1779 and was originally known as San Miguel Church. The Santa Monica Church complex includes the convent connected to the church by an elevated three-level brick stairway.
The parish church of Santa Monica is renowned as the largest church in the whole Ilocos Norte province, most especially the length of the nave. In June 1983, the church was the setting for the grand wedding of Gregorio Araneta and Irene Marcos, the daughter of then President Marcos. It was declared as an Important Cultural Property by the National Museum of the Philippines on September 27, 2009.
Sarrat used to be a visita of Laoag. It was originally named as San Miguel to mark the arrival of the first Augustianian missionaries in Sarrat during the feast of Saint Michael the Archangel on September 29, 1724. The parish of Santa Monica de Sarrat was erected in 1724. It was only in 1769 when the convent was built to serve as a temporary chapel. The church, belfry, convent, and the curillo or bridge staircase connecting the church and convent was simultaneously constructed and finished in 1779.
During the 1950s, Father Clemente Tabije supervised the reinforcement of the roof by putting massive posts inside. Former first Lady Imelda Marcos spearheaded restoration work for the church on June 1977. In March 3, 1816, the church was destroyed with just a few jewels saved by the Father Juan Casas. Father Vicente Barreiro, who was the prior in 1818, worked for five years and finished the reconstruction of the convent in 1817. Father Isidro Champaner rebuilt the church in 1848. The church buildings burned again on 1882 and were repaired by Father Leandro Collado during his long assignment from 1875 to 1895.

A few months after the wedding of Irene Marcos and Gregorio Araneta, a devastating earthquake hit the province of Ilocos Norte which recorded a magnitude of 5.3 on the Richter scale and an intensity 7 on the Rossi-Forel scale on August 17, 1983 . The tremor sustained a major structural damage on the church's facade as well as toppling down the bell tower. The church underwent restoration and repair after the earthquake.
