The Army of the Western Pyrenees (Armée des Pyrénées occidentales) was one of the Republican French armies of the French Revolutionary Wars. From April 1793 until 12 October 1795, the army fought in the Basque Country and in Navarre during the War of the Pyrenees. After indecisive fighting during the first year of its existence, the army seized the Spanish port of San Sebastián in August 1794. By the time the Peace of Basel was signed on 22 July 1795, the Army of the Western Pyrenees held a significant portion of northeastern Spain.
The army commanders with the longest tenure were Jacques Léonard Muller, who served from October 1793 to August 1794, and Bon-Adrien Jeannot de Moncey, who served from August 1794 until the army was disbanded. Emperor Napoleon appointed Moncey a Marshal of France in 1804 during the First French Empire.
