Louis Brisson (23 June 1817 – 2 February 1908) was a French Roman Catholic priest and the founder of both the Oblate Sisters of Saint Francis de Sales and the Oblates of Saint Francis de Sales. He founded the female branch alongside Léonie Aviat and the male branch alongside the Servant of God Thérèse Chappuis. Brisson's founding of the orders stemmed from his desire to improve the working conditions of middle-class girls and to ensure their protection and the promotion of their faith.
