In the title compound, C(20)H(12)BrFO(2)S, the 4-fluoro-phenyl ring makes a dihedral angle of 2.63 (6)° with the mean plane of the benzofuran fragment. The dihedral angle between the phenyl ring and the mean plane of the benzofuran fragment is 84.60 (6)°. In the crystal, mol-ecules are linked by weak inter-molecular C-H⋯O hydrogen bonds, and slipped π-π inter-actions between the benzene rings of neighbouring mol-ecules [centroid-centroid distance = 3.719 (3) Å, inter-planar distance = 3.000 (3) Å and slippage = 1.520 (3) Å].
