The Triomphant was an 80-gun ship of the line of the French Navy. Laid down in Toulon in March 1778 by the designer-builder Joseph-Marie-Blaise Coulomb, she was launched on 31 March 1779 and completed in June 1779. She took part in the Battle of Martinique with the Comte de Guichen's fleet in 1780 and served in the American War of Independence. She was captured at Toulon by the Anglo-Spanish forces in August 1793, and was burnt there on 18 December 1793 during the evacuation of the port. Her remains were refloated in 1805 and broken up.
