Allan Glen's School was a state‑funded secondary school located in the Townhead district of Glasgow, Scotland. Established in 1853 as a technical school for the sons of tradesmen, it was named after the philanthropist Allan Glen (1798–1868), who bequeathed funds for the education of Glasgow’s working‑class youth. The school operated under the control of the Glasgow School Board and later the Glasgow Corporation, providing a curriculum that emphasized science, engineering, and practical subjects alongside the broader secondary education requirements.
The institution functioned as a selective grammar school from the 1950s, admitting pupils based on academic performance. In 1972, following educational reforms in Scotland that promoted comprehensive schooling, Allan Glen's School was merged into the newly created Allan Glen's High School, which continued to occupy the original premises. The high school retained the technical and scientific focus of its predecessor while offering a wider range of subjects.
Allan Glen's School closed permanently in 1996 as part of further restructuring of Glasgow’s secondary education system. The original school buildings were subsequently refurbished and incorporated into the City of Glasgow College campus, where they are used for further and higher education courses.
Notable alumni of Allan Glen's School include several individuals who achieved prominence in engineering, science, and the arts, reflecting the institution’s historical emphasis on technical education. The school’s legacy persists in the continued use of its facilities for education and in the ongoing recognition of Allan Glen’s contributions to Glasgow’s educational development.
