'''Butadieno''' lau karbono-atomo eta bi lotura bikoitz dituen [[hidrokarburo]]a (CH<sub>2</sub>=CH-CH=CH<sub>2</sub>). Usainik eta kolorerik ez duen gasa da, [[ur]]etan eta [[etanol]]etan nekez disolbatzen dena, eta azetonatan, [[eter]]retan eta [[bentzeno]]tan, berriz, aise disolbatzen dena. Industrian goma sintetikoak egiteko erabiltzen da, eta [[nylon]]aren sintesian bitarteko bezala. Petrolioaren ''craking''ean lortzen da.
