The Legion of Mary is a lay apostolic association devoted to prayer, evangelization, and active service in the Church. Founded in 1921 in Dublin, Ireland, it operates worldwide under the spiritual patronage of Virgin Mary.

Members meet regularly for prayer and planning, and they undertake works such as visiting the sick, encouraging inactive Catholics, supporting parish activities, and promoting devotion to Our Lady. The Legion emphasizes discipline, humility, and faithful commitment to apostolic work.

Through prayer and service, the Legion of Mary contributes actively to the spiritual growth of the parish and the wider mission of the Church.
