In the Catholic Church, several locations around the world invoke the patronage of the Immaculate Conception. Catholic diocesan authorities with the expressed and written approval of the Pope in countries including Brazil, Korea, the Philippines, Portugal, Spain, and the United States of America designate the Blessed Virgin Mary as their principal patroness.
As part of the patronage, the Feast of the Immaculate Conception is often observed both religiously and culturally within these countries. Numerous national parades, processions and cultural festivities are associated with this patronage ranging from public holidays to holy day of obligation. Several Popes have conferred this title of patronage, sometimes initiated by bishops.
The list below enumerates the various countries by which the Pope, through a papal bull has formally granted the Immaculate Conception as the patroness of the people and its land or kingdom.
The list of Pontifical declaration does not include Ireland, Nicaragua and Portugal.
The Virgin Mary is the official patroness of Brazil under the title Our Lady of Aparecida (Our Lady of Immaculate Conception (who) Appeared). The image associated with this patronage received a canonical coronation on 8 December 1904 with approval from Pope Pius X.
