In the title compound, C17H15ClO2S, the 3-chloro­phenyl ring makes a dihedral angle of 84.48 (4)° with the mean plane [r.m.s. deviation = 0.004 (1) Å] of the benzofuran fragment. In the crystal, mol­ecules are linked by weak C—H⋯O, C—H⋯π and C—S⋯π [3.414 (2) Å] inter­actions. The crystal structure also exhibits weak π–π inter­actions between the furan rings of neighbouring mol­ecules [centroid–centroid distance = 3.826 (2), inter­planar distance = 3.447 (2) and slippage = 1.660 (2) Å].
