'''Etilenoa''' CH<sub>2</sub>=CH<sub>2</sub> formula duen [[hidrokarburo]] asegabea da. Lotura bikoitza duten hidrokarburoen ([[alkeno]]en) arteko lehena eta bakunena da.
 
Etilenoa polimerizatu egiten da, [[polietileno]]ak emateko; azken horiek [[plastiko]]ak dira. Etilen kloruroak ere ezagutzen diren plastiko hedatuenak lortzeko erabiltzen dira, hain ezaguna den poli(binil kloruroa) ([[PVC]]) lortzeko batez ere.
