A corrole is an aromatic organic chemical, whose structure is in the form of the corrin ring which is also present in vitamin B₁₂. The ring consists of nineteen carbon atoms, with four nitrogen atoms in the core of the molecule.

Corrole normally serves as a trianionic ligand with transition metals.

Corroles can be obtained in organic synthesis by a condensation reaction of a benzaldehyde with pyrrole in a water / methanol / hydrochloric acid mixture to an open-ring bilane or tetrapyrrane followed by oxidation and ring closure with p-chloranil ^[1]:
