Bergamotenes are a group of isomeric chemical compounds with the molecular formula C15H24.

There are two structural isomers, α-bergamotene and β-bergamotene, which differ only by the location of a double bond.

α-Bergamotene is found in the oils of carrot, bergamot, lime, citron, cottonseed, and kumquat.

[4][5] In a more complex relationship, the tobacco plant Nicotiana attenuata emits α-trans-bergamotene from its flowers at night to attract the tobacco hawk moth (Manduca sexta) as a pollinator; however, during the day the leaves produce α-trans-bergamotene to lure predatory insects to feed on any larvae and eggs that the pollinator may have produced.

Bergamotenes, in turn, are intermediates in the biosynthesis of more complex chemical compounds.
