Catholic Theological Union (CTU) is aprivate Catholic graduate school oftheology inChicago, Illinois, United States. It was formed inHyde Park as a union of schools from three Catholicreligious institutes and has since been sponsored by 24 institutes and Catholic faith communities. It is one of the largest Catholic graduate schools of theology in the English-speaking world, training men and women for both lay and ordained ministry within the Catholic Church.[5] It gained renewed attention in 2025 when alumnus Robert Francis Prevost, who earned aMaster of Divinity degree in 1982, was electedPope Leo XIV.[6]
During the 1970s and 1980s, there was a movement among some Union students and faculty in support of theordination of women within the Catholic Church; this included organizing a meeting on the CTU campus in 1976 of theWomen’s Ordination Conference and staging a protest at a 1981 ordination event at the nearbySt. Thomas the Apostle Catholic Church, with the latter being one of the events that led the Vatican to order an investigation of American Catholic seminaries.[6]
The school granted its first Master of Divinity degree to a woman in 1981.[6]
