In the title compound, C17H16ClNO2, the N=C—O—C—C fragment is planar within 0.029 (1) Å, and makes dihedral angles of 66.71 (8) and 59.61 (8)° with the planes of the chloro­phenyl and benzoyl rings, respectively. The carbonyl C=O bond is not coplanar with either of the aromatic rings; it makes angles of 42.5 and 23.5° with the normals to the ring planes. In the crystal, very weak C—H⋯O, C—H⋯Cl, C—H⋯π and π–π [inter­planar distance = 3.53 (1) Å] inter­actions are observed.
