Queen of Heaven () is a title given to the Virgin Mary, by Christians mainly of the Catholic Church and, to a lesser extent, in Anglicanism, Lutheranism, and Eastern Orthodoxy. The title has long been a tradition, included in prayers and devotional literature and seen in Western art in the subject of the Coronation of the Virgin from the High Middle Ages, long before it was given a formal definition status by the Church.

Ad caeli reginam states that the main principle on which the royal dignity of Mary rests is her Divine Motherhood. ... So with complete justice St. John Damascene could write: "When she
