The Diocese of Imus is a Catholic diocese in the Philippines that comprises the entire province of Cavite. By the virtue of the apostolic constitution Christi Fidelium, promulgated by Pope John XXIII, the diocese was canonically erected on November 25, 1961, when it was excised from the Archdiocese of Manila and the then-diocese, now Archdiocese of Lipa. The diocese was formally inaugurated on April 26, 1962 and its first bishop, Artemio Gabriel Casas, took canonical possession of its administration. Imus Cathedral, located along General Castañeda Street in the poblacion of Imus, serves as the see of the diocese. It is one of twelve cathedrals founded by the Order of Augustinian Recollects in the Philippines.
