Allylbenzene or 3-phenylpropene is an organic compound with the formula C₆H₅CH₂CH=CH₂. It is a colorless liquid. The compound consists of a phenyl group attached to an allyl group. Allylbenzene isomerizes to trans-propenylbenzene.^[3]

In plant biochemistry, the allylbenzene skeleton is the parent (simplest representation) of many phenylpropanoids. Prominent allylbenzenes include eugenol, safrole, and many others.^[4]
