The Apostolic Vicariate of Jolo is a Latin Catholic missionary pre-diocesan jurisdiction in the Sulu province on Mindanao island, Philippines.
It's exempt, i.e. directly dependent of the Holy See (notably Roman Congregation for the Evangelization of Peoples), not part of any ecclesiastical province.
Its cathedral episcopal see is the Marian Cathedral of Our Lady of Mount Carmel, in Jolo, Sulu, Autonomous Region in Muslim Mindanao (ARMM).
Established on 28 October 1953 as Apostolic Prefecture of Sulu, of territory split off from the then Territorial Prelature of Cotabato and Sulu (now diocese of Cotabato).
Promoted and renamed after its see on 1958.07.12 as Apostolic Vicariate of Jolo, hence entitled to a titular bishop.
