In the title compound, C24H15NO3, the fused naphthaquinone–pyrrole unit is approximately planar, the naphthaquinone ring system making a dihedral angle of 2.91 (10)° with the pyrrole ring. The plane of the pyrrole ring makes a dihedral angle 61.64 (14)° with that of the benzene ring of the benzoylmethylene group. The crystal structure is stablized by intramolecular C—H⋯O interactions.
