Thomas Joseph Shahan (September 11, 1857 – March 9, 1932) was an American Roman Catholic theologian and educator, born at Manchester, New Hampshire, educated at Collège de Montréal (1872) at the Pontifical North American College, and at the Propaganda in Rome.

He studied at the Roman Seminary (J.U.L., 1889) and at the University of Berlin (S.T.D., 1891), then served as professor of Church law and patrology at The Catholic University of America (1891–1909) and as rector of the university (1909–1928). It was under his rectorship that African American students were barred from the university. He was also president of the Catholic Educational Association in 1909-14 and of the National Conference of Catholic Charities in 1910-14. In 1914 he was appointed auxiliary bishop of Baltimore, and ordained titular bishop of Germanicopolis on 15 November that year.

Professor Shahan was an editor of the Catholic Encyclopedia (published in 1913), editor in chief of The Catholic Historical Review from its foundation in 1915 until 1928, and one of the editors of Universal Knowledge: A Dictionary and Encyclopedia of Arts and Sciences, History and Biography, Law, Literature, Religions, Nations, Races, Customs and Institutions (New York: Universal Knowledge Foundation, 1927).
