In the title thio­urea derivative, C16H17N3OS, the hy­droxy- and methyl-substituted benzene rings form dihedral angles of 9.62 (12) and 55.69 (6)°, respectively, with the central CN3S chromophore (r.m.s. deviation = 0.0117 Å). An intra­molecular O—H⋯N hydrogen bond ensures the coplanarity of the central atoms. The H atoms of the NH groups are syn and the conformation about the N=C double bond [1.295 (4) Å] is E. In the crystal, helical supra­molecular chains sustained primarily by N—H⋯S hydrogen bonds are found. Additional stabilization is provided by C—H⋯π and π–π [ring centroid(hy­droxy­benzene)⋯ring centroid(methyl­benzene) = 3.8524 (18) Å] inter­actions
