A scapular is a Western Christian garment suspended from the shoulders. There are two types of scapulars, the monastic and devotional scapular; both forms may simply be referred to as "scapular". As an object of popular piety, a scapular serves to remind wearers of their commitment to live a Christian life.

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.
