In the title compound, C(15)H(11)Cl(2)NO(2), the dihedral angle between the two benzene rings is 74.83 (5)°. The N-bound and terminal benzene rings are inclined at dihedral angles of 4.09 (10) and 78.38 (9)°, respectively, to the mean plane through the acetamide group. Intra-molecular C-H⋯O and N-H⋯O hydrogen bonds both generate S(6) rings.
