Scoil Maelruain was founded in 1976 by Fr. Basil Turner.

The late Fr. Basil Turner O.P., when asked why he named our school “Scoil Naomh Maelruan” he replied, that he thought the name was appropriate as it would honour the memory of the original Naomh Maelruan whose name has been linked with Tallaght for a thousand years.
