Bergamotenes are a group of isomeric chemical compounds with the molecular formula C₁₅H₂₄. The bergamotenes are found in a variety of plants, particularly in their essential oils.

There are two structural isomers, α-bergamotene and β-bergamotene, which differ only by the location of a double bond. Both of these isomers have stereoisomers, the most common of which are known as the cis and trans-isomers (or endo- and exo-isomers).

α-Bergamotene is found in the oils of carrot, bergamot, lime, citron, cottonseed, and kumquat.^[1]^[2]
