The American College of the Immaculate Conception, or the American College of Louvain is a former Roman Catholic seminary in Leuven, Belgium. Founded in 1857, it was operated by United States Conference of Catholic Bishops (USCCB) to prepare European priests for service in the United States and to provide a residence for Americans priests studying at the Catholic University of Louvain. The American College closed in June 2011 due to low enrollment and a faculty shortage; its building was turned over to the Katholieke Universiteit Leuven (KU Leuven) for student housing.
