John XXIII College is a Roman Catholic co-educational primary and secondary day school located in Mount Claremont, a western suburb of Perth, Western Australia. The school provides education from kindergarten to Year 12 students and operates under the authority of the Catholic Archbishop of Perth.
The college is the result of the merger in 1977 of the Jesuit Saint Louis boys school spread over different campuses (first opened in 1938) and Loreto Convent girls school (first opened in 1897). In 1986 the school was relocated to its present site in Mount Claremont.
