History The Apostolic Prefecture of Mindoro was created on July 2, 1936, with territories taken from the Roman Catholic Dioceses of Jaro and Lipa, both of which were later elevated into archdioceses.
On July 12, 1951, Pope Pius XII, through the papal bull Merit ab Apostolic, elevated the apostolic prefecture to an apostolic vicariate.
On December 19, 1974, and January 27, 1983, portions of its territory were lost to the creation of the Diocese of Romblon and the Apostolic Vicariate of San Jose in Mindoro.
On March 25, 2026 Pope Leo XIV has elevated the Apostolic Vicariate of Calapan to a diocese and appointed its apostolic vicar, Moises Cuevas, as its first bishop. The diocese was canonically erected on August 7, 2026.
