St. John's Institution (; abbreviated SJI) is a public all-boys school (sixth form is co-ed) and is one of the oldest schools in Kuala Lumpur, Malaysia. The school is widely known by its initials SJI and the students of St John's Institution bear the name Johannians. While it is commonly thought that the school is named after Jean-Baptiste de la Salle, the founder of the De La Salle Christian Brothers Order and also known as the Patron Saint of Teachers; the school actually takes it name from St. John the Evangelist which is the sponsoring parish church/cathedral which is also located nearby on Jalan Bukit Nanas. SJI consists of a primary school and a secondary school. The primary and secondary schools initially were fee paying missionary schools and remained as such until the 1970s. They functioned together until the increase in enrolment of pupils led to a separation of the primary school in 1960. The primary schools were formerly known in Malay as Sekolah Kebangsaan St. John (1) and Sekolah Kebangsaan St. John (2) until the primary schools were officially merged again recently. The newly merged primary school is known today in Malay as Sekolah Kebangsaan St. John. The secondary school was called Sekolah Menengah Kebangsaan St. John, but it was announced in April 2016 that the name would be reverted to St John's Institution, a decision widely applauded by alumni and backed by another Johannian, Sultan Nazrin Shah of Perak. SJI is among the first 30 schools selected into the Cluster School scheme when it was first introduced in 2007 by the Ministry of Education, Malaysia. The La Sallian Brothers and the Board of Governors still hold much autonomy over management of the secondary school compared to the Malaysian Ministry of Education. This has allowed the secondary school to maintain a certain amount of prestige. Though the school land is owned by the Roman Catholic Church (including St. John's Cathedral, Kuala Lumpur which is next to the school), much of the school funding is received from the Government of Malaysia.
