In the title compound, C16H13IO3S, the dihedral angle between the planes of the benzo-furan ring system [r.m.s. deviation = 0.015 (2) Å] and the 4-methyl-phenyl ring is 70.35 (5)°. In the crystal, mol-ecules are linked by pairs of π-π inter-actions between the furan and benzene rings, with centroid-centroid distances of 3.667 (3) and 3.701 (3) Å. The mol-ecules stack along the a-axis direction. In addition, pairs of C-H⋯O hydrogen bonds between inversion-related dimers [which generate R 2 (2)(10) loops] and a short I⋯I [3.7534 (3) Å] contact are observed.
