In the crystal of the title compound, C14H9Cl2NO2, inversion-related dimers with R22(8) ring motifs are formed by intermolecular O—H...O hydrogen bonding. The 3-aminobenzoic acid group and the 2,4-dichlobenzaldehyde moiety subtend a dihedral angle of 55.10 (2)°. The H atom of the carboxyl group is disordered over two sites with equal occupancies.
