'''Eten''' je [[nenasičeni aciklični ogljikovodiki|nenasičen acikličen ogljikovodik]] in [[alken]] z molekulsko formulo C<sub>2</sub>H<sub>4</sub>. Med ogljikoma se nahaja dvojna vez, na vsak ogljikov atom pa sta vezana še dva vodika. Vrelišče etena je −105 °C. Če razbijemo dvojno vez in ničesar ne dodamo dobimo [[monomer]] etena, ki se imenuje [[etilen]]. Pri spajanju več monomerov dobimo polimer, ki se imenuje [[polietilen]].
