In the title compound, C(15)H(13)ClN(2)OS, the dihedral angles between the sulfourea group and the benzene ring and the chloro-benzene ring are 35.8 (6) and 81.6 (6)° respectively. An intra-molecular N-H⋯O inter-action occurs. In the crystal, a combination of inter-molecular π-π stacking inter-actions [centroid-centroid distance = 4.0616 (16) Å] and N-H⋯S hydrogen bonds stabilizes the structure.
