'''甲乙醚'''（{{lang-en|ethyl methyl ether}}），或稱'''甲基乙基醚'''、'''甲氧基乙烷'''（{{lang-en|methoxyethane}}），是一种结构简单的[[醚]]，分子式C<sub>3</sub>H<sub>8</sub>O，结构简式C<sub>2</sub>H<sub>5</sub>OCH<sub>3</sub>，和[[丙醇]]是[[同分异构体]]。 甲乙醚是一种有药味的无色气体，吸入可引起[[窒息]]或头晕。作为[[路易斯碱]]，它可以与[[路易斯酸]]反应形成盐，与氧化剂发生剧烈反应。

== 合成 ==
甲乙醚可由[[溴甲烷]]和[[乙醇钠|乙醇鈉]]（或其他的[[乙醇盐|乙醇鹽]]）透過[[威廉姆逊合成反应|威廉姆遜合成反應]]製備而成，該反應由[[双分子亲核取代反应|雙分子親核取代反應]]的機理而進行。
