The arrondissement of Rochefort was created in 1800. At the January 2017 reorganisation of the arrondissements of Charente-Maritime, it gained one commune from the
arrondissement of La Rochelle, one commune from the
arrondissement of Saintes and three communes from the
arrondissement of Saint-Jean-d'Angély, and it lost two communes to the arrondissement of La Rochelle. As a result of the reorganisation of the
cantons of France which came into effect in 2015, the borders of the cantons are no longer related to the borders of the arrondissements. The cantons of the arrondissement of Rochefort were, as of January 2015: •
Aigrefeuille-d'Aunis • Le Château-d'Oléron •
Marennes • Rochefort-Centre • Rochefort-Nord • Rochefort-Sud • Royan-Est • Royan-Ouest • Saint-Agnant • Saint-Pierre-d'Oléron •
