亚克兴角（古希腊语：Ἄκτιον，Aktion；拉丁语：Actium）是古罗马地名，为位于今日的希腊西岸阿卡纳尼亚西北部的一个海角。公元前31年该处爆发亚克兴角战役，屋大维击败安东尼，开创罗马帝国。

Actium (Greek: Ἄκτιον) was the ancient name of a promontory of western Greece in northwestern Acarnania, at the mouth of the Ambracian Gulf). Actium is chiefly famous as the site of the naval Battle of Actium, in which Octavian won a decisive victory over Mark Antony on September 2, 31 BC.
