The molecule of the title compound, C11H7ClO3, is planar, with a maximum deviation of 0.0383 (10) Å from the naphthoquinone plane. An intramolecular O—H...O hydrogen bond generates an S(6) ring motif. The crystal packing is stabilized by intermolecular C—H...O hydrogen bonds. Short intramolecular Cl...O [2.8234 (8) Å] and O...O [2.5530 (11) Å], and intermolecular Cl...Cl [3.2777 (3) Å] contacts further stabilize the crystal structure.
