The Battle of Sant Llorenç de la Muga (in Catalan, in Spanish: San Lorenzo de la Muga) was fought on 13 August 1794 between an attacking Spanish–Portuguese army led by the Conde de la Unión and a French army commanded by Jacques François Dugommier. The local French defenders headed by Pierre Augereau and Dominique Pérignon repulsed the allies. The Spanish garrison of Fort de Bellegarde surrendered a month later.
