Amphion was a 50-gun ship of the line of the French Navy.
Amphion took part in the Battle of Ushant on 27 July 1778 under Keredern de Trobriand.[1] Seriously damaged, Amphion returned to Brest while the fight was still raging, carrying the first news of the battle.[2] In consequence, Trobriand was replaced at the command of Amphion.[3]
She took part in the Battle of Grenada on 6 July 1779,[4][5] where her captain, Ferron du Quengo, was killed.[6] The same month, she ran aground at Cap-Haïtien at Saint-Domingue.[1]
Amphion took part in the action of 20 March 1780, along with Annibal, Diadème and Réfléchi.[1][7]
Amphion was broken up in Rochefort in 1787.[1]
