Bretagne was a large 110-gun three-decker French ship of the line, built at Brest, which became famous as the flagship of the Brest Fleet during the American War of Independence. She was funded by a don des vaisseaux grant by the Estates of Brittany. She was active in the European theatres of the Anglo-French War and of the French Revolutionary Wars, notably taking an important role in the Glorious First of June. Later, she took part in the Croisière du Grand Hiver and was broken up.

The Glorious First of June, also known as the Fourth Battle of Ushant, was the first and largest fleet action of the naval conflict between the Kingdom of Great Britain and the First French Republic during the French Revolutionary Wars.
