Zenovie Pâclișanu (1 May 1886 – 1957 or 1958) was an Austro-Hungarian-born Romanian historian, diplomat and cleric. A native of Transylvania, he completed a doctorate at Vienna, and during the 1910s was active in the cultural and religious life of Blaj. Following the creation of Greater Romania, which he enthusiastically supported, he became a civil servant, twice taking part in treaty negotiations. After World War II, the new communist regime suppressed his Greek-Catholic Church and threw Pâclișanu in prison, where he died. His work, banned under communism but partly re-edited in the years since, focuses on the history of Transylvania between the 17th and 19th centuries, particularly in the religious sphere.
