槲叶环（拉丁语：corona civica）是一种以橡树叶编织而成的花冠状头冠，这在古罗马时代是一项第二高等奖励品。它被颁授于那些以实际行动拯救同袍于危难中的罗马公民。

The Civic Crown (Latin:corona civica) was a chaplet of common oak leaves woven to form a crown. During the Roman Republic and the subsequent Principate, it was regarded as the second highest military decoration to which a citizen could aspire (the Grass Crown being held in higher regard). It was reserved for Roman citizens who saved the lives of fellow citizens by slaying an enemy on a spot held by the enemy that same day. The citizen saved must admit it; no one else could be a witness.
