Blackrock College

Blackrock College is a voluntary day and boarding Catholic secondary school for boys aged 13–18, in Williamstown, Blackrock, County Dublin, Ireland. It was founded by French missionary Jules Leman in 1860 as a school and later became also a civil service training centre.

The college, 7 kilometres from Dublin city centre, is just in from the sea, and is self-contained, with boarding and teaching facilities in 56 acres of parkland. It accommodates approximately 1,000 day and boarding students. As of 2021, Blackrock is run by the Congregation of the Holy Ghost in close co-operation with a dedicated group of lay personnel.
