The Congregation of Marian Fathers of the Immaculate Conception of the Most Blessed Virgin Mary (Latin: Congregatio Clericorum Marianorum ab Immaculata Conceptionis Beatissimae Virginis Mariae) is a Catholic male clerical religious congregation founded, 1670, in Poland. It is also known as Marians of the Immaculate Conception. Its members add the post-nominal letters M.I.C. after their names to indicate membership in the Congregation.

The Congregation of about 500 priests and brothers has convents in 19 countries on 6 continents. Marians pledge support to the Pope and follow the official teachings of the Catholic Church and aim to spread devotion to Blessed Virgin Mary as the Immaculate Conception, pray for the souls in purgatory and undertake a variety of apostolic work.

The Marians were the first Catholic religious institute for men dedicated to honor Mary’s Immaculate Conception. The community traces its roots to Stanislaus of Jesus and Mary Papczyński who was beatified in Basilica of Our Lady of Licheń, Licheń Stary, Poland, in 2007, and canonized on 5 June 2016 at Saint Peter's Square in Vatican City by Pope Francis. As an Institute of consecrated life, their motto is Pro Christo et Ecclesia.

They are also the official promoters of the Divine Mercy message since 1941.
