Xavier College is a Roman Catholic, day and boarding school predominantly for boys, with its main campus located in Kew, an eastern suburb of Melbourne, Victoria, Australia. Xavier was founded in 1872 by the Society of Jesus, beginning classes in 1878, and is part of the international network of Jesuit schools begun in Messina, Sicily in 1548. Originally an all-boys school, the College now offers co-education until Year 4, and an all-boys environment from then on.
