The Army of the Coasts of Brest () was a French Revolutionary Army formed on 1 April 1793 by splitting the Army of the Coasts into this army and the Army of the Coasts of Cherbourg. It was put under the command of Jean Baptiste Camille de Canclaux and charged with combatting the Chouans and protecting the coasts of Brittany against a British invasion (repulsing the Quiberon landing). Canclaux was removed from his post on 1 October that same year and replaced with Alexandre Dumas, who asked to be relieved of his command due to the War in the Vendee. He was replaced by Jean Léchelle and then in August 1794 by Lazare Hoche.
