Germacrenes are a class of volatile organic hydrocarbons, specifically, sesquiterpenes. Germacrenes are typically produced in a number of plant species for their antimicrobial and insecticidal properties, though they also play a role as insect pheromones. Two prominent molecules are germacrene A and germacrene D.

Germacrene has five isomers.

The essential oil of the red deadnettle (Lamium purpureum) is characterized by its high contents of germacrene D, as is Clausena anisata.
