This article provides a contextualized study of teenage (14–18 years old) Acadian feminist activism in New Brunswick, a particularly marginalized subject in studies. Based on extensive archives of the prominent francophone youth associations of the province, Activités-Jeunesse and the Fédération de la jeunesse francophone du Nouveau-Brunswick, the author analyses the issues, agendas and sociability network of feminist activism in French-speaking secondary schools of the province from 1971 to 2020.
