The Roman Catholic Diocese of Sorsogon (Latin: Dioecesis Sorsogonensis) is a diocese of the Latin Church of the Roman Catholic Church in the Philippines. The diocese was established in 1951 by the Archdiocese of Caceres, and in 1968, the diocese was subdivided after the Diocese of Masbate separated. The diocese is a suffragan of the Archdiocese of Caceres.

The volcano of Bulusan is surmounted by the keys and the sword that represent Saints Peter and Paul respectively who are titulars of the cathedral. The book with the lily surrounded by fishes represent Saint Anthony of Padua, Doctor of the Church and patron saint of the capital of Masbate which is within the territory of the diocese (until 1968). The fishes allude to one of the miracles attributed to the saint while still alive: when men did not listen to his preaching, he went to preach to the fishes which lifted up their heads above the water in rapt attention.
