The Army of the Eastern Pyrenees was one of the French Revolutionary armies. It fought against the Kingdom of Spain in Roussillon, the Cerdanya and Catalonia during the War of the Pyrenees. This army and the Army of the Western Pyrenees were formed by splitting the original Army of the Pyrenees at the end of April 1793 soon after the war started. Shortly after the Peace of Basel on 22 July 1795, the fighting ended and the army was dissolved on 12 October that same year. Many of its units and generals were transferred to join the Army of Italy and fought under Napoleon Bonaparte in 1796.

The French Revolutionary Army was the French land force that fought the French Revolutionary Wars from 1792 to 1802. In the beginning, the French armies were characterised by their revolutionary fervour, their poor equipment and their great numbers. However, the French Revolutionary Army had become arguably the most powerful army in the world by the mid-1790s, as the French armies had become well-experienced and organized, enabling them to comfortably outfight their enemies.
