Réalt na Mara National School is a co-educational, vertical primary school located in Mill Street, Dundalk, Co Louth. The school was built and opened in October 1954, following the closure of the old Convent School. It amalgamated with Réalt na Mara Junior School and Réalt na Mara Senior School in September 2009 to become Réalt na Mara National School.

In 1999, the school embarked on a pioneering initiative, establishing a Centre for Autism within its mainstream school. This center provides specialized education and support for children with autism, allowing them to integrate and participate in various activities alongside their peers. Réalt na Mara National School follows an adapted curriculum for its Center for Autism Class but also ensures that students have the opportunity to make their First Confession and Communion with their peers.

Additionally, the school offers a range of subjects including Art, P. E., and Music. Under the leadership of Principal Mr.

Phil McCaul, Réalt na Mara National School is committed to providing a nurturing and inclusive learning environment for all students
