Limonene () is a colorless liquid aliphatic hydrocarbon classified as a cyclic monoterpene, and is the major component in the fragrance and essential oil of citrus fruit peels, taking its name from Italian limone ("lemon").

Limonene is a chiral molecule, and most biological sources produce just one enantiomer (isomer). The (+)-isomer, d-limonene, which is the (R)-enantiomer, occurs more commonly in nature in citrus fruit peels, the principal commercial source, from which it is obtained commercially by two primary methods: centrifugal separation and steam distillation. D-limonene is used as a flavoring agent in food manufacturing, in chemical synthesis as a precursor to carvone, and as a renewables-based solvent in cleaning products.
