St Aloysius' College is a selective fee-paying, private, Jesuit day school in Glasgow, Scotland. It was founded in 1859 by the Jesuits, who previously staffed the college, and named after Saint Aloysius Gonzaga. St Aloysius' College is a co-educational school with a kindergarten, junior school, and senior school.

The school was established on 12 September 1859 at Charlotte Street, near Glasgow Green, in the East End of Glasgow. Here lived the city's largely migrant Catholic community from Ireland and the Scottish Highlands, both of which groups the school was intended to serve. Since 1866, the College's main campus has been situated in Garnethill on the north side of Glasgow city centre, adjacent to the Glasgow School of Art. Originally, the school was for boys only. In 1979, the admission policy was changed by the Governors during the tenure of Headmaster Fr. Henry Anthony Richmond SJ and girls were admitted. Girls now make up half of the school population.

Buildings include the original category-B listed Italianate Chandlery Building, including the administration block, library, and refectory. Its 1908 and 1926 extensions are known collectively as The Hanson Building, which accommodates classrooms for languages and the humanities as well as the school chapel and gymnasium.

The Mount Building, which originally housed the city's first Royal Hospital for Sick Children from 1882, which previously housed the junior school (whose patron is St John Ogilvie) as well as music, art and drama and the kindergarten. As of August 2023, The Mount Building is no longer being used by the school and Music, Art and Drama facilities have all been moved to the convent building, referred to by the school as the Performing Arts Centre, or PAC, while the kindergarten is now its own building.

More modern additions include the Clavius Building housing the Mathematics, Science, and Technology faculty and the Junior School Building, both of which have won RIBA architectural awards, and have been identified as amongst the best modern Scottish buildings.

In 2011, the number of buildings and the size of the campus increased with the acquisition of the Mercy Convent site and buildings. The building houses the schools music and art classrooms, as well as a drama and recording studio.

The school has a close relationship with the Jesuit parish church of St Aloysius next door. The church is regularly used by the college and Masses offered for both the junior and senior schools. The building is listed category A, designed by C. J. Menart in the baroque revival style and modelled on the Church of the Gesú, original Jesuit headquarters in Rome.

A new Sports Hall was recently constructed on the College campus, and open for use from August 2017. The school's main sports grounds are on the north-eastern outskirts of the city at Millerston.
