In the title compound, C17H15ClO2S, the 3-chloro­phenyl ring makes a dihedral angle of 71.46 (4)° with the mean plane of the benzofuran fragment. In the crystal, mol­ecules are linked by weak C—H⋯O hydrogen bonds and a slipped π–π inter­action between the 3-chloro­phenyl rings of adjacent mol­ecules [centroid–centroid distance = 3.630 (2) Å, inter­planar distance = 3.375 (2) Å and slippage = 1.337 (2) Å].
