St Michael's College (Irish: Coláiste Naomh Mícheál) is a voluntary Catholic boys' school, with an associated primary school, located on Ailesbury Road in Dublin 4, Ireland. Founded in 1944 by the Congregation of the Holy Spirit (The Spiritans) as a second feeder school along with Willow Park, it was initially a primary school to Blackrock College. The first eight pupils were transferred from Willow Park. The next September, 58 boys were enrolled. In 1952 the first secondary school pupils were admitted. Following expansion in the 1960s and 1970s, the school developed both a primary and secondary school. It has been extensively expanded, including the opening of a cafeteria, a sports pavilion, as well as new classrooms and a new gym.
