In the title compound, C15H12Cl2N2O, the atoms not making up the chlorobenzene ring are approximately coplanar (r.m.s. deviation = 0.073 Å). The dihedral angle between these 13 atoms and the chlorobenzene ring is 67.37 (10)°. The C=O and Csp2-Cl groups are almost eclipsed [Cl-C-C=O = -6.5 (3)°]. In the crystal, C(6) chains linked by C-HO hydrogen bonds result in  chains.
