beta-Pinene (β-pinene) is a monoterpene, an organic compound found in plants. It is one of the two isomers of pinene, the other being α-pinene. It is colorless liquid soluble in alcohol, but not water. It has a woody-green pine-like smell.

This is one of the most abundant compounds released by forest trees.[4] If oxidized in air, the allylic products of the pinocarveol and myrtenol family prevail.[5]
