Annibale Bugnini CM (14 June 1912 – 3 July 1982) was a Roman Catholic prelate. Ordained in 1936 and named archbishop in 1972, he was secretary of the commission that worked on the reform of the Catholic liturgy that followed the Second Vatican Council. Critics of the changes made to the Catholic Mass and other liturgical practices before and after Vatican II consider him a controversial figure. He held several other posts in the Roman Curia and ended his career as papal nuncio to Iran, where he acted as an intermediary during the Iran hostage crisis of 1979 to 1981.
