The MN Jeanne d'Arc (R97) was a unique helicopter cruiser of the Marine Nationale. She was the third vessel of the French Navy named after Joan of Arc ("Jeanne d'Arc", in French), a national heroine of France and saint of the Catholic Church who repelled the English invasion during the Hundred Years' War.
In peacetime, Jeanne d'Arc was used for teaching and training purposes; however, in case of emergency or crisis, she was to have become a fully capable helicopter cruiser. Toward the end of her service life Jeanne d'Arc became unsuitable for the role due to the increasing size and weight of helicopters.
Jeanne d'Arc was built as La Résolue, as her predecessor, Jeanne d'Arc of 1930, was still in service. She was renamed Jeanne d'Arc in 1964. The ship was retired in May 2010 and decommissioned in September 2010.
She was succeeded by an aircraft carrier of the same name.
