Chrysene is a polycyclic aromatic hydrocarbon (PAH) with the molecular formula C₁₈H₁₂ that consists of four fused benzene rings. It is a natural constituent of coal tar, from which it was first isolated and characterized. It is also found in creosote, a chemical used to preserve wood.

Chrysene is formed in small amounts during the burning or distillation of coal, crude oil, and plant material.
