The University of St. Thomas (also known as UST or St. Thomas) is a coeducational archdiocesan Roman Catholic institution of higher learning based in St. Paul, Minnesota. Founded in 1885 as a Catholic seminary, it is named after St. Thomas Aquinas, a medieval Catholic theologian and philosopher who is the patron saint of learners in the Roman Catholic Church. Now a university, it currently enrolls more than 11,000 students, making it Minnesota's largest private college or university. St. Thomas' mission statement is as follows:

"Inspired by Catholic intellectual tradition, the University of St. Thomas educates students to be morally responsible leaders who think critically, act wisely, and work skillfully to advance the common good."

Father Dennis Dease became the 14th president of the University of St. Thomas on July 1, 1991.
