Archbishop Gaetano Alibrandi (14 January 1914 - 3 July 2003) of the Roman Catholic Church was a senior papal diplomat and former personal secretary to Giovanni Battista Montini (later Pope Paul VI). Alibrandi served from 1969 to 1989 as the Apostolic Nuncio to the Republic of Ireland. In that role he clashed with the governments of Liam Cosgrave (1973-77) and Garret FitzGerald (1981-82, 1982-87), both of whom accused him of being too sympathetic to Irish republicans.
