In the title compound, C17H15FO2S, the 3-fluorophenyl ring makes a dihedral angle of 86.89 (4)° with the mean plane of the benzofuran fragment. In the crystal, molecules are linked by weak intermolecular C—H⋯O hydrogen bonds. The crystal structure also exhibits a slipped π–π interaction between the furan rings of neighbouring molecules [centroid–centroid distance = 3.719 (2) Å, interplanar distance = 3.475 (2) Å and slippage = 1.325 Å].
