The Diocesan Shrine and Parish of Our Lady of the Pillar, commonly known as Imus Cathedral, is a Roman Catholic cathedral church in the city of Imus, in the province of Cavite, Philippines. The church serves as the seat of the bishop of the Diocese of Imus, the diocese that has jurisdiction over the entire Civil Province of Cavite.

Enshrined inside the cathedral is the canonically crowned image of Nuestra Senora del Pilar de Imus (Our Lady of the Pillar). The said title of the Blessed Virgin Mary serves as the titular patroness of the Diocese of Imus, Province of Cavite, as implied by then pope, now a saint, John XXIII. John the Baptist is also considered the secondary patron saint of the city. The current parish priest and rector of the cathedral is Reuel Castañeda, vicar general of the diocese.

The church itself features the longest Holy Week procession in the province of Cavite, with at least 70 floats and the country's 5th longest overall (the other four being the St Augustine Parish, Baliuag, and San Isidro Labrador, Pulilan, both located in the province of Bulacan, with at least 110 floats per parish, The Our Lady Of the Abandoned in Marikina, with 82 floats, and The Our Lady of Aranzazu San Mateo, Rizal with 76 floats). Currently, the cathedral is being elevated into Cathedral Shrine.

In 1616, the Augustinian Recollects arrived in Imus and established a convent. The parish of Imus started as a chapel-of-ease in Brgy. Toclong, a sub-parish (visita) of Cavite Viejo (now Kawit, Cavite). Recollect Father Pedro de San Buenaventura petitioned the government to convert Imus into an independent municipality in 1774. Imus, though, did not become a separate town and parish until October 3, 1795. Its poblacion (town center) and a provisional church was first established in an area currently known as Brgy. Bayan Luma (Tagalog for 'Old Town'). The parish was under the order of the Augustinian Recollects with Francisco de Santiago, O.A.R., its first assigned priest.

During the leadership of Fr. Nicolas Becerra, who served from 1821 to 1840, he advocated the move of the town center to Brgy. Balangon, its present location. The construction of the parish church of Imus on the new location was started in 1823 using forced labor. The structure was made from stone and bricks. Its facade was patterned after the fifth Manila Cathedral by Fr. Juan de Uguccioni, which existed from 1760 to 1852.

The early fathers were preoccupied with not just religious matters but also of economic concerns. The friars gradually bought parcels of land while some of these lands were donated by rich families. The Recollects were the first ones to buy parcels of land beginning in 1666 and their haciendas came to being in 1812. These areas, comprising the Hacienda de San Juan de Imus or the Hacienda de Imus (Imus Estate), grew to include the whole towns of Imus, Dasmariñas, and Brgy. Binakayan in Kawit. The estate house of the hacienda, or the house of the friars, was located along Imus River (at the present day Cuartel) at the southern end of the Bridge of Isabel II, a Spanish bridge built by the priest-engineers of the Recollects. Citizens of Imus were required to pay rent to live and tilled the lands of Imus.

The Hacienda de Imus was sold by the Recollect Corporation on March 31, 1894, to the Fomento de la Agricultura de Filipinas (Promotion of Agriculture in the Philippines), a corporation in Madrid, for 4,000,000 pesetas. It was later sold to the British Manila Estates Company, which eventually sold it to the U.S. controlled Philippine government for $1,045,000 in U.S. currency for distribution to the Filipinos, to win their favor, and to pacify the revolutionaries. The Church of Imus became secular in 1897.

By virtue of the Apostolic Constitution Christi fidelium promulgated by Pope John XXIII on November 25, 1961, Cavite was created a separate bishopric from Manila after more than three hundred years. On April 26, 1962, the Diocese of Imus was formally erected and established. The then parish church of Imus was chosen to become the cathedral of the diocese, the seat of the bishop of Cavite, with the Virgin Mary under her title Our Lady of the Pillar, its titular patroness. The first leader of the diocese and bishop of Cavite is Artemio Casas, originally from Meycauayan, Bulacan.

The current bishop of Imus is Reynaldo G. Evangelista, previously bishop of the Diocese of Boac and a native of Batangas, who was appointed by Pope Francis on April 8, 2013, his first pontifical appointment in the Philippines. He replaced Bishop Luis Antonio Tagle (whose paternal ancestry is from Imus) after his installation as the Archbishop of Manila in December 12, 2011. Evangelista was installed as the fifth bishop of Imus on June 5, 2013.

The cathedral was declared a structure of historical significance with the placing of a historical marker by then National Historical Institute of the Philippines on November 13, 2006.

The image of the patroness of the Imus Cathedral, Our Lady of the Pillar of Imus, was canonically crowned on December 3, 2012, by Cardinal Luis Antonio Tagle. It was originally scheduled for November 26 but the elevation of Tagle into a cardinal by Pope Benedict XVI necessitated the move.
