In Ireland today, Marists are involved in a wide range of ministries.

Marists minister in three schools, Chanel College Coolock and CUS Leeson Street, both in Dublin and St Mary's College in Dundalk Co. Louth. The current policy of the Marist Fathers in relation to these schools is outlined in the MEA - MARIST EDUCATION AUTHORITY: Roles Responsibilities and Authority. Marist involvement in these schools continues at the level of Trustee, members of Board of Management, principals, Chaplains and teachers.

Marist Fathers have responsibility for three parishes, St Teresa's Parish Donore Ave and St Brendan's Parish Coolock in Dublin, and Holy Family Parish in Dundalk, Co Louth. . Individual Marists are also curates in various parishes in the Diocese of Dublin and Armagh. We also provide church services in CUS Leeson St. and St Mary's Dundalk.

Marist involvement in Third Level education is through a number of Marists working in All Hallows College, Milltown Institute, and Marino Institute of Education.

Individual Marists work in the areas of Spiritual Direction, Counselling, Social Ministry, Family Therapy and other Therapies. One Marist is chaplain in the Irish Army.

Traditionally nearly a third of Irish Marists have worked abroad in other mission areas, mostly Oceania. Now as well as Oceania, Irish Marists have also made themselves available for missionary work in countries like: Peru/Venezuela, Cameroon/Senegal, Philippians, Brazil, and the International Team in Notre Dame de France in London.
