The title compound, C(10)H(6)ClNO(2), has a dihedral angle of 46.46 (5)° between the benzene and maleimide rings. A short inter-molecular halogen-oxygen contact is observed, with a Cl⋯O distance of 3.0966 (13) Å. Both CO groups are involved in two C-H⋯O inter-actions, which gives rise to sheets parallel to (100). In addition, these sheets exhibit a π-π stacking inter-action between the benzene and maleimide rings [mean inter-planar distance of 3.337 (3) Å].
