Edward Ignatius Devitt SJ (November 26, 1840 – January 26, 1920) was a Canadian American priest, Jesuit, and historian of the American Catholic Church. Born in Saint John, New Brunswick, he moved with his family to Boston, Massachusetts, at a young age. He studied in public schools in the city before enrolling at the College of the Holy Cross. Devitt spent two years there, and then entered the Society of Jesus in 1859. He studied at the novitiate in Frederick, Maryland, and at the newly opened Woodstock College. He briefly taught at the Washington Seminary during his studies, and after graduating, was a professor for the next thirty years at Holy Cross, Woodstock, and Georgetown University.
