The Fontenoy was a 90-gun Suffren-class Ship of the line of the French Navy. She was the only in French service named in honour of Battle of Fontenoy.
She was part of the Toulons squadron until 1871, when she was converted into a prison hulk for prisoners of the Paris Commune.
In 1878, her engines were removed and she became a transport. Her name changed to Bretagne and she was used as a boys' school ship for the École des mousses.
She was eventually decommissioned in 1892 and broken up in 1911.
