Charles William Lyons SJ (January 31, 1868 – January 31, 1939) was an American Catholic priest who became the only Jesuit and likely the only educator in the United States to have served as the president of four colleges. Born in Boston, Massachusetts, he attended the local public schools before entering the wool industry. He abandoned his career in industry to enter the Society of Jesus. While a novice in Maryland, he suffered a nervous breakdown and was sent to Georgetown University as prefect. He then resumed his studies at Woodstock College, teaching intermittently at Gonzaga College in Washington, D.C. and Loyola College in Baltimore. After his ordination, he became a professor at St. Francis Xavier College in New York City and at Boston College.
