The Immaculate Heart of Mary is a Roman Catholic devotion which refers to the view of the interior life of Mary, her joys and sorrows, her virtues and hidden perfections, and, above all, her virginal love for God the Father, her maternal love for her son Jesus Christ, and her motherly and compassionate love for all mankind. Traditionally, the Immaculate Heart is depicted pierced with seven swords or wounds, in homage to the seven dolors of Mary and roses, usually red or white, wrapped around the heart.

Catholic devotions are particular customs, rituals, and practices of worship of God or honour of the saints which are in addition to the liturgy of the Catholic Church. The United States Conference of Catholic Bishops describes devotions as "expressions of love and fidelity that arise from the intersection of one's own faith, culture and the Gospel of Jesus Christ". Devotions are not considered part of liturgical worship, even if they are performed in a church or led by a priest, but rather they are paraliturgical. The Congregation for Divine Worship at the Vatican publishes a Directory on Popular Piety and the Liturgy.
