The Latin Patriarchate of Jerusalem (Latin: Patriarchatus Latinus Hierosolymitanus) is the Latin Catholic ecclesiastical patriarchate in Jerusalem, officially seated in the Church of the Holy Sepulchre. The Latin patriarch of Jerusalem is the archbishop of Latin Church Catholics of the Archdiocese of Jerusalem with jurisdiction for all Latin Catholics in Israel, Palestine, Jordan and Cyprus; he also holds the office of grand prior of the Order of the Holy Sepulchre. It is exempt, being directly subject to the Holy See (and exceptionally its Dicastery for the Eastern Churches, which normally handles Eastern Catholics). It is not within an ecclesiastical province, and has no metropolitan functions.
The Patriarchate was originally established in 1099, with the Kingdom of Jerusalem encompassing the territories in the Holy Land newly conquered by the First Crusade. From 1374 to 1847 it was a titular see, with the patriarchs of Jerusalem being based at the Basilica di San Lorenzo fuori le Mura in Rome. Pope Pius IX re-established a resident Latin patriarch in 1847.
