San Vicente Parish Church, also known as the Archdiocesan Shrine of Saint Vincent Ferrer, is a Roman Catholic church in the municipality of San Vicente, Ilocos Sur, Philippines. It is under the jurisdiction of the Archdiocese of Nueva Segovia. The church enshrines a miraculous image of Saint Vincent Ferrer in the main retablo. The present church is built in 1795 after the main town was founded. The town was formerly a barrio of Vigan known as Barrio Tuanong.

In 1795 came the installation of the seat of municipality and the church, and Bo. Tuanong became San Vicente de Ferrer. Don Pedro de Leon was the first parish priest and he was believed as the initiator of the construction of the church of San Vicente. Years then, the image of the titular, was found in fishing nets. Devotees report miracles coming from the saint, causing more local devotees to flock at his shrine to ask for favors from him.

The church is baroque in style, with two towers and two layers of columns in the facade. The bell towers with three storeys are octagonal, having a resemblance to the bell tower of Vigan. It has four bells hung in each tower. Inside, a pulpit can be found and there are three retablos; one is dedicated to the Virgin Mary, one to the Sacred Heart of Jesus, and the image of Vincent Ferrer is enshrined at the central, main retablo.
