卡塔隆平原战役（英语：Battle of the Catalaunian Plains），又称沙隆战役（英语：Battle of Châlons），于451年发生在当今法国的香槟沙隆地区（Châlons-en-Champagne），罗马将军埃提乌斯和西哥特国王狄奥多里克一世的联军与由阿提拉率领的匈人联军作战。这次战役是西罗马帝国最后一次大型的军事行动，亦是埃提乌斯军事生涯上的顶峰。战役虽以西罗马帝国联军胜利告终，但狄奥多里克一世却于此战阵亡，而此役后阿提拉亦离开了高卢并将目标再指向意大利本土。

The Battle of the Catalaunian Plains (or Fields), also called the Battle of Châlons or the Battle of Maurica, took place in CE 451 between a coalition led by the Roman general Flavius Aetius and the Visigothic king Theodoric I against the Huns and their allies commanded by their leader Attila. It was one of the last major military operations of the Western Roman Empire, although Germanic federates composed the majority of the allied Roman army. The battle was strategically inconclusive: the Romans stopped the Huns' attempt to establish vassals in Roman Gaul, and installed Merovech as king of the Franks. However, the Huns successfully looted and pillaged much of Gaul and crippled the military capacity of the Romans and Visigoths. The Huns were later destroyed by a coalition of their Germanic vassals at the Battle of Nedao in 454.
