St. Mary's Grammar School is a grammar school in Magherafelt, County Londonderry, Northern Ireland.
St. Mary's was founded in 1927 by the Sisters of the Holy Family of Bordeaux. Ten girls were enrolled in the first year under the principalship of Sister Tracey. The school grew throughout the 1940s under the principalship of Sister Marie Therese Harte. With the school's continued academic success, the need for more accommodation became urgent and in 1954 the first extension was built.
September 1978 marked a significant milestone in the history of the school: 37 boys were enrolled in St. Mary's along with 587 girls.
In 1984, new accommodation was again required. Under the leadership of the then principal Sister Immaculata O'Connor, the Friends of St. Mary's was formed with the purpose of raising funds to finance the building programme. The £6 million extension was formally opened by Cardinal Daly on 8 December 1994. It includes a large sports hall, fitness suite, science block, technology block, drama/lecture theatre, careers suite, Sixth Form study area and general purpose classrooms. Tennis courts, grass and all-weather pitches complement the indoor sports facilities. In 2003, the school trustees completed a further phase of the development programme when Cafe Bordeaux and a new classroom extension were opened.
Today, St. Mary's Grammar School has over eleven hundred pupils on roll, with an equal ratio of boys and girls and serves three counties: Londonderry, Antrim and Tyrone.
September 2004 marked another beginning in the school's history with the appointment of its first male Principal, Mr D A Lambon.[1] In September 2011, Deirdre Gillespie was appointed principal.
In September 2022, Paul McClean was appointed new principal, taking over from acting principal Frank Dunlop, who filled in for Mrs Gillespie.
