Queen of Heaven is a title given to the Virgin Mary by Christians mainly of the Roman Catholic Church, and also, to some extent, in Eastern Orthodoxy and Anglicanism. The title is a consequence of the First Council of Ephesus in the fifth century, in which the Virgin Mary was proclaimed "theotokos", a title rendered in Latin as Mater Dei, in English "Mother of God".

The Catholic teaching on this subject is expressed in the papal encyclical Ad Caeli Reginam, issued by Pope Pius XII. It states that Mary is called Queen of Heaven because her son, Jesus Christ, is the king of Israel and heavenly king of the universe; indeed, the Davidic tradition of Israel recognized the mother of the king as the Queen Mother of Israel. The Eastern Orthodox Churches do not share the Catholic dogma, but themselves have a rich liturgical history in honor of Mary.

The title Queen of Heaven has long been a Catholic 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.

Queen of Heaven (Latin Regina Caeli) is one of many Queen titles used of the Virgin Mary. The title derived in part from the ancient Catholic teaching that Mary, at the end of her earthly life, was bodily and spiritually assumed into heaven, and that she is there honored as Queen.
