金刚烷胺（英语：Amantadine）是美国FDA所批准的抗病毒和抗帕金森病药。金刚乙胺与金刚烷胺有着相似的结构和性质。

根据美国疾病控制与预防中心的数据，100%的季节性H3N2流感和2009年H1N1流感大流行的流感病毒样本对金刚烷胺有耐药性。在美国，金刚烷胺不再被推荐作为感冒药。另外，金刚烷胺抗帕金森病的效果仍不确定，2003年en:Cochrane Review指出没有充分的证据证明金刚烷胺抗帕金森病的效果和安全性。

Amantadine (trade name Symmetrel, by Endo Pharmaceuticals) is a drug that has U.S. Food and Drug Administration approval for use both as an antiviral and an antiparkinsonian drug. It is the organic compound 1-adamantylamine or 1-aminoadamantane, meaning it consists of an adamantane backbone that has an amino group substituted at one of the four methyne positions. Rimantadine is a closely related derivative of adamantane with similar biological properties.
