剑栏之战（Battle of Camlann、又称作卡姆兰战役）是传说中亚瑟王的最后一战。不久前因追击兰斯洛特而负伤的高文在这场战斗中被莫德雷德击杀，战役的最后，亚瑟王虽杀死了叛乱的莫德雷德，但自己也受了致命的重伤并在不久后死去。由于关于这场战役的记载非常少，一些历史学家对这场战役的真实性表示怀疑。关于这场战役的最早记载来自《Annales Cambriae》一书，书中记载这场战斗发生于537年。这场战役的具体地点也未有定论，可能的地点包括萨默塞特的女王般地（Queen Camel）等。

The Battle of Camlann (Welsh:Cad Camlan or Brwydr Camlan) is reputed to have been the final battle of King Arthur, in which he either died or was fatally wounded, fighting his enemy Mordred (who was, in some later versions of the tale, his son or his nephew).
