The Canon de 42 cm modèle 1875 or canon de 420 mm modèle 1875 was a built-up gun made by Schneider-Creusot and the Ruelle Foundry in the late nineteenth century. This gun was the highest calibre gun put into service on a vessel of the French Navy. Together with the canon de 450 mm/45 modèle 1920 and the 431 mm modèle 1939 it was one of the few guns over 400 mm calibre developed for the Marine Nationale.
