St. John's Institution (abbreviated SJI) or formerly known as St. John's National Secondary School () 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 its name from St. John the Evangelist Church which sponsors their surrounding parish 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 such until the 1970s. They functioned together until the increase in pupil enrollment led to the 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 was among the first 30 schools selected for 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 more autonomy over the 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.

Site and architecture The main school building is located in Jalan Bukit Nanas, in the city centre of Kuala Lumpur, next to the Bukit Nanas Forest Reserve, giving it a lush setting. St. John's Primary Schools are located across the road from the main school building. While the Convent Bukit Nanas, an Infant Jesus Sisters' school for the girls, the AIA building, and the Archdiocese of Kuala Lumpur are located further down the road. The Fatima Kindergarten (housed in what is Kuala Lumpur's oldest Catholic church and now converted into a community service centre) and the Roman Catholic St John's Cathedral are located on the road leading up to SJI.

The school is famous for its imposing red and white brick main building with Grecian-Spanish influences where it has been recognized as a Kuala Lumpur Heritage Building since 1986, where else it was gazetted as a National Heritage Site by the Government of Malaysia on 21 May 2010 through National Heritage Department.

Administration The school has traditionally been headed by the brothers of the La Sallian order, with a brother director (like a headmaster) and a brother supervisor (like a deputy headmaster). In recent years, the brother supervisor was replaced with three assistant principals, who are not in the La Sallian order.

History +YearEvents1904 On 18 January 1904, at the earnest request of the Education Department and the then Bishop of Malacca, Mgr. Fee, the La Sallian Brothers opened a school in Kuala Lumpur. The Staff consisted of three Brothers and three lay masters. According to the Malay Mail, Sir Hugh Clifford who visited St. John's in August 1927 recalled that it started with an initial enrolment of 18 boys. On 15 January, three days before classes were to commence, three Brothers arrived to take charge of the school – Brother Julian Francis from Hong Kong, Brother Andrew Corsini from Burma and Brother Cyril Alexander from Penang. The school building was a two-storeyed wooden structure, 80 feet long and 20 feet wide, with brick pillars and a verandah facing the north. Later in the year, Brother James Gilbert arrived from Singapore to take the place of Brother Julian Francis as Brother Director of St. John's Institution1905On 2 January 1905, the school reopened with an additional staff member, Brother Vernier Augustus. A Standard 7 was set up and entrusted to Brother Cyril Alexander. With this new set-up, expansion was needed. So Father Renard lent to the school the house of the Chinese Catechist which was capable of holding one class and also an attap shed near the site now occupied by the Telecoms. In August 1905, Brother Felix Paulian arrived to join the staff1906In June 1906, Brother Imier of Jesus, Provincial Visitor of the United States paid a visit to St. John's . He later became Superior General in 1913. As the school rapidly increased in numbers, the Brothers began to look for a suitable site for a new building. Meanwhile, more classes were opened and accommodated in temporary structures. Finally the government provided a piece of land given to the mission for religious and educational purposes. The building was designed by fellow staff member, Brother V. Augustus On 3 November, the foundation stone for the new building was laid by Sir Henry Conway Belfield, Resident Councilor for Selangor.1907 After much difficulty and delay, the new building was finally completed and officially declared open by the High Commissioner and Governor, Sir John Anderson on 10 August 1907. At the end of the year, the new building was advanced enough to be used for the Cambridge Examination for all the candidates of Kuala Lumpur.1908 Brother Gilbert was given a short but well deserved rest in Ceylon and the school was left temporarily in the charge of Brother Augustine. Brother Gilbert also intended to start a Science Laboratory but his intention was not fulfilled because during his absence, Brother V. Augustus on whom he had been relying for the scheme had been transferred to St. Xavier's Institution in Penang1914 The Brothers' Building was enlarged by the addition of two new wings which were to house the chapel and offices and the Juniorate and Novitiate. Brother Marcian Cullen was appointed Director of the newly formed Juniorate.1915A Cadet Corps was formed followed shortly by a Scout Troop which unfortunately did not last very long1916Brother Gilbert who continued in office till 1916 had cherished the dream of a swimming pool in the valley south of the school, but financial and other difficulties prevented his fulfilment He also started a fund for the construction of a school hall, but the outbreak of World War I checked his efforts—and those of his successors, too. In November 1916, Brother Claude Marie Guibert replaced Brother Gilbert as Director and remained in office till his transfer to Malacca in 19211921 Brother Stephen Edward Buckley (Director 1921–1925) demolished the Brothers' Building and replaced it with the present one, to which additions were made later.1925 Brother Louis, who was appointed Sub-Director in December 1924, took Brother Stephen's place in 1925 and remained until his transfer in 1930. He initiated the plan of enlarging the playground by filling up part of the valley, but the success of this enterprise was reserved for his successor, Brother Cornelius. The golden statue of Jean Baptiste De La Salle, the founder of the Brothers as it stands in front of the famous red and white Romanesque style building of St. John's Institution which is an iron cast statue, arrived from France in February 1925 and was installed the same year in a ceremony carefully conducted by Rev. Father L. Duvell under the watch of Brother Louis1930Brother Cornelius Nulty served as Brother Director from 1930 to 1946 and under his energetic management, many projects were brought to a successful conclusion. Brother Cornelius enlarged the playground, a project that was started by Brother Louis. He then turned his attention to the building of the hall which was finally completed in 1936 with the provision for two more storeys in the future.
