Saint Gabriel's College (Thai: โรงเรียนเซนต์คาเบรียล) is a private Catholic all-boys school in Bangkok, Thailand.

In 1918, after the First World War ended, the demand for schools and education in Bangkok sharply increased.

At that time, the Brothers of Saint Gabriel had established only one school in Bangkok, Assumption College.

As a response to increasing demand, Brother Martin de Tours proposed opening a new school in Bangkok.

He accepted a plot of land offered by Father Brozat of the nearby Saint Francis Xavier Church in Samsen as the site for his vision.
