3-Carene is a bicyclic monoterpene consisting of fused cyclohexene and cyclopropane rings. It occurs as a constituent of turpentine, with a content as high as 42% depending on the source. Carene has a sweet and pungent odor, best described as a combination of fir needles, musky earth, and damp woodlands.

A colorless liquid, it is not soluble in water, but miscible with fats and oils. It is chiral, occurring naturally both as the racemate and enantio-enriched forms.
