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].
