The North American Center for Marianist Studies provides resources to people interested in the Marianist Family—including brothers, sisters, priests, and lay people—and to Marianist ministries. Through programs, publications, research, and a special library collection, NACMS strives to link the vision of the Marianist Founders—William Joseph Chaminade, Adèle de Batz de Trenquelléon, and Marie Thérèse de Lamourous—to the contemporary Church and world.

NACMS is sponsored by the Society of Mary, the Catholic religious order that founded the University of Dayton.
