The Army of the Coasts of Brest () was a French Revolutionary Army formed on 30 April 1793 by splitting the "Army of the Coasts" into this army and the "Army of the Coasts of Cherbourg". The formation was first put under the command of Jean Baptiste Camille Canclaux and charged with fighting the War in the Vendée, combatting the Chouannerie and protecting the coasts of Brittany against a British invasion. After successfully defending Nantes and suffering setbacks at Tiffauges and Montaigu, Canclaux was recalled on 5 October 1793 and many of the army's soldiers were absorbed into the Army of the West. Over the next few years, Jean Antoine Rossignol, Jean-François-Auguste Moulin, Thomas-Alexandre Dumas, Lazare Hoche and Gabriel Venance Rey led the army in turn. In June–July 1795 the army crushed a Royalist invasion at Quiberon. On 5 January 1796 the formation and two other armies were merged into the "Army of the Coasts of the Ocean" and placed under the command of Hoche.
