Perylene or perilene is a polycyclic aromatic hydrocarbon with the chemical formula C₂₀H₁₂, occurring as a brown solid. It or its derivatives may be carcinogenic, and it is considered to be a hazardous pollutant. In cell membrane cytochemistry, perylene is used as a fluorescent lipid probe. It is the parent compound of a class of rylene dyes.
