In the title compound, C 19 H 10 ClNO 4 , the dihedral angle between the naphtho­quinone and coumarin rings is 48.99 (6)°. In the crystal, mol­ecules are linked by strong N—H⋯O hydrogen bonds into chains with graph-set motif  C (6) along [101]. The packing also features π–π stacking inter­actions between naphtho­quinone and coumarin rings [centroid-to-centroid distances = 3.7679 (12) and 3.6180 (13) Å].
