St. Xavier's Institution, at Farquhar Street in George Town, Penang, Malaysia, is the oldest Lasallian school in Southeast Asia and one of the Catholic Lasallian schools in Malaysia. While it has a history dating back to 1787, the present-day institution, named after St. Francis Xavier, was only established in 1852. To this day, St. Xavier's Institution maintains its historical rivalry with Penang Free School, another premier school in George Town which holds the honour of being Malaysia's oldest school. The school has two suburban feeder primary schools at Pulau Tikus and Air Itam.
