The Congregation of Holy Cross (Latin: Congregatio a Sancta Cruce) is a Catholic congregation of missionary priests and brothers founded in 1837 by Blessed Basil Moreau, in Le Mans, France. Members of the congregation add the nominal letters C.S.C. after their names to indicate that they are members of the congregation.
Father Moreau also founded the Marianites of Holy Cross, now divided into three independent congregations of sisters. The Congregations of women who trace their origins to Father Moreau are the Marianites of Holy Cross (Le Mans, France), the Sisters of the Holy Cross (Notre Dame, Indiana), and the Sisters of Holy Cross (Montreal, Quebec, Canada).
