'''Fenchone''' is an organic compound classified as a monoterpenoid and a ketone. It is a colorless oily liquid. It has a structure and an odor similar to those of camphor. Fenchone is a constituent of absinthe and the essential oil of fennel. Fenchone is used as a flavor in foods and in perfumery.<ref name=Ullmann>Karl-Georg Fahlbusch, Franz-Josef Hammerschmidt, Johannes Panten, Wilhelm Pickenhagen, Dietmar Schatkowski, Kurt Bauer, Dorothea Garbe, Horst Surburg "Flavors and Fragrances" in Ullmann's Encyclopedia of Industrial Chemistry, Wiley-VCH, Weinheim: 2002.

Other names for fenchone include ''dl''-fenchone and (±)-fenchone. It is a mixture of the enantiomers ''d''-fenchone and ''l''-fenchone. Other names for ''d''-fenchone include (+)-fenchone and (1''S'',4''R'')-fenchone. Other names for ''l''-fenchone include (−)-fenchone and (1''R'',4''S'')-fenchone. The ''d''-fenchone enantiomer occurs in pure form in wild, bitter and sweet fennel plants and seeds, whereas the ''l''-fenchone enantiomer occurs in pure form in wormwood, tansy, and cedarleaf.<ref name=Flavour_Fragr>U.
