Oxepin is an oxygen-containing heterocycle consisting of a seven-membered ring with three double bonds. The parent C₆H₆O exists as an equilibrium mixture with benzene oxide. The oxepin–benzene oxide equilibrium is affected by the ring substituents.^[1] A related dimethyl derivative exists mainly as the oxepin isomer, an orange liquid.^[2]

Oxepin is an intermediate in the oxidation of benzene by the cytochrome P450.^[3] Other arene oxides are metabolites of the parent arene.
