Hélène Brion (27 January 1882 – 31 August 1962) was a French teacher, feminist, socialist and communist.
She was one of the leaders of the French teachers' union.
During World War I (1914–18) she was arrested for distributing pacifist propaganda, given a suspended sentence and dismissed from her job as a teacher.
She visited Russia soon after the Russian Revolution, and wrote a book on her experiences.
It was never published.
She devoted much of her effort in later years to preparing a feminist encyclopedia, which was never completed or published.
