Most Anglicans, among other Christian denominations, patronize the Anglican Rosary, although the use of the Roman Catholic Rosary is fairly common among Anglicans of Anglo-Catholicchurchmanship. Many Anglo-Catholic prayer books and manuals of devotion contain the Roman Catholic Rosary along with other Marian devotions. The public services of the Anglican churches, as contained in the Book of Common Prayer, do not directly invoke the Blessed Virgin or any other saint in prayer, but Anglicans are free to do so in their private devotions. Anglicans who pray the Roman Catholic Rosary tend not to use the Luminous Mysteries or the Fatima decade prayer.

There is also a chaplet in use among some Anglicans that consists of four "weeks" of seven beads each, on which a variety of different prayers may be said. Though this is sometimes called the "Anglican rosary," it is not to be confused with the Holy Rosary of Our Lady as prayed by Anglicans and other Western Christians.

Rosary in the Lutheran church:

The Lutheran Church encourages its members to pray the rosary. However, though the Church follows the same format of the rosary as the Roman Catholics, each "Hail Mary" is replaced with the "Jesus Prayer". The only time the "Hail Mary" is said is at the end of the mysteries on the medal, where it is then replaced with the "Pre-Trent" version of the prayer (which ommits "Holy Mary, mother of God, pray for us sinners, now and at the hour of our death"). The final "Hail Mary" can also be replaced by reciting of either the Magnificat, or Martin Luther's "Evangelical praise of the Mother of God".
