'''Etilena oksida''', juga dikenal '''oksirana''' adalah [[senyawa organik]] dengan [[rumus molekul]] {{chem|C|2|H|4|O}}. Senyawa ini berjenis [[eter]] siklik. Etilena oksida berbentuk gas tak berwarna mudah terbakar pada [[Suhu kamar|suhu ruangan]] dan berbau manis. Senyawa ini merupakan [[epoksida]] paling sederhana: cincin tiga-anggota dengan 1 [[oksigen]] dan 2 [[karbon]]. Karena struktur molekulnya ini, etilena oksida banyak dipakai pada [[reaksi adisi]], seperti [[polimerisasi]]. Etilena oksida berisomer dengan [[asetaldehida]] dan [[vinil alkohol]].

Etilen oksida pertama kali disintesis oleh Wurtz tahun 1859 dan kemudian dikenal dengan proses klorohidrin. Produksi pertama '''etilen oksida''' secara komersial dimulai tahun 1914 hingga sekarang. Tahun 1931, Lefort mengembangkan proses oksidasi langsung yang menggeser keberadaan proses klorohidin hingga sekarang.<ref name=Ullmann>Rebsdat, Siegfried and Mayer, Dieter (2005) "Ethylene Oxide" in ''Ullmann's Encyclopedia of Industrial Chemistry''.
