St. Louis School was a Catholic boys' school in Claremont, Western Australia, between 1938 and 1976.
The school was founded by the Jesuitstheir only school in Western Australia in 1987. It was previously a private property called Hinemoa, purchased in 1901 by Alexander Clarke Munro, who was manager of the Jarrahdale Timber Station, became Superintendent of the Millars Karri and Jarrah Company and was the Western Australian Government's representative at the Paris and Glasgow 1901 Exhibition. The homestead building was used for the junior school, while new buildings were erected to house the senior school, the Jesuit community, and the boarders.
The school was named after Aloysius Gonzaga, an early Jesuit saint, also known as LuÃÂs de Gonzaga. Its motto was ().
The Jesuits ran the school until 1971, when it was handed over to the Catholic Archdiocese of Perth. Archbishop Lancelot Goody appointed a school council chaired by Judge John Lavan to manage the school.
St. Louis School amalgamated with the Loreto Convent girls' school to form John XXIII College, which opened in 1977.
The site of St. Louis School is now occupied by the St. Louis Retirement Estate, which has preserved the old Administration building.
St. Louis School enrolled boys from ages seven to seventeen, both day pupils and boarders.
Until the mid-1960s, the year grades were named after levels in the traditional Jesuit curriculum: Elements, Rudiments, Poetry and Rhetoric.
Initially there were three houses named after the Jesuit saints: Gonzaga (blue), Kostka (green) and Xavier (red). A fourth house Loyola (white) was introduced in 1976 to ease the amalgamation with Loreto Convent which already had a fourth house.
Former pupils of St. Louis School are known as Old Louisians. Notable alumni include:
