Un poliè és un hidrocarbur alifàtic o cíclic insaturat que contenen dos o més enllaços dobles carboni-carboni.

Els poliens amb dos dobles enllaços consecutius, s'anomenen al·lens. Per exemple el propadiè o al·lè, de fórmula . Els que tenen tres o més dobles enllaços consecutius es denominen cumulens, com ara el butatriè o el pentatretraè . Si contenen dos dobles enllaços no consecutius, reben el nom de diens o diolefines, per exemple l'1,3-butadiè .[1]
