Dibenzodioxin, C12H8O2, is an organic heterocyclic compound in which two benzene rings are attached to a dioxin ring.

The name generally refers to the dibenzo-p-dioxin, as no detailed information is available on the dibenzo-o-dioxin isomer, expected to be highly unstable with peroxide-like characteristics.

Dibenzodioxin forms the scaffold for the class of chemicals known collectively as dioxins, which include the potent toxins polychlorinated dibenzodioxins (PCDDs) such as 2,3,7,8-tetrachlorodibenzodioxin.
