Universalis Ecclesiae was a papal bull of 29 September 1850 by which Pope Pius IX recreated the Roman Catholic diocesan hierarchy in England, which had been extinguished with the death of the last Marian bishop in the reign of Elizabeth I. New names were given to the dioceses, as the old ones were in use by the Church of England. The bull aroused considerable anti-Catholic feeling among English Protestants.

A papal bull is a type of public decree, letters patent, or charter issued by a pope of the Catholic Church. It is named after the leaden seal (bulla) that was traditionally appended to the end in order to authenticate it.
