The Battle of Mas Deu or Battle of Mas d'Eu on 19 May 1793 saw the French Revolutionary Army of the Eastern Pyrenees under Louis-Charles de Flers fighting Bourbon Spain's army of Catalonia led by Antonio Ricardos.

The Spanish drove the outnumbered French soldiers out of their camp near Mas Deu and compelled them to retreat to Perpignan. The victory enabled the Spanish forces to lay siege to the Fort de Bellegarde, which dominated the best road through the Pyrenees from Barcelona into France. For the next month, Ricardos was preoccupied by the Siege of Bellegarde. Mas Deu is a former Knights Templar establishment east of the town of Trouillas in Pyrénées-Orientales. The action was fought during the War of the Pyrenees, part of the War of the First Coalition.
