The Nativity of the Blessed Virgin Mary, the Nativity of Mary, Marymas or the Birth of the Virgin Mary, refers to a Christian feast day celebrating the birth of Mary, mother of Jesus.

According to apocrypha, as well as Christian and Islamic tradition, Saint Anne was the mother of Mary, the wife of Joachim and the maternal grandmother of Jesus. Mary's mother is not named in the Bible's canonical gospels. In writing, Anne's name and that of her husband Joachim come only from New Testament apocrypha, of which the Gospel of James seems to be the earliest that mentions them. The mother of Mary is mentioned but not named in the Quran.
