Diocese of Malolos

The Diocese of Malolos (Latin: Dioecesis Malolosinae; Tagalog: Diyosesis ng Malolos; Spanish: Diócesis de Malolos) is a Latin Church ecclesiastical jurisdiction or diocese of the Catholic Church in the Philippines, encompassing the whole Province of Bulacan and Valenzuela City in metropolitan Manila and is a suffragan to the metropolitan Archdiocese of Manila. The mother church of the Diocese is the Cathedral-Basilica of the Immaculate Conception located in Malolos City, Bulacan.^[2] The Blessed Virgin Mary, under the title of Immaculate Conception is the principal patroness of the diocese.

It was excised from the Archdiocese of Manila on December 11, 1961, by Pope John XXIII and was officially established on March 11, 1962, upon the installation of Manuel P. del Rosario, then-Bishop of Calbayog, by Salvatore Siino, the papal nuncio, as the first bishop of the diocese. Since August 21, 2019, the current and fifth Bishop of Malolos is Dennis C. Villarojo, who was appointed by Pope Francis on May 14, 2019.
