The title compound, C10H10N4OS, is nearly planar with the mean planes of the hy-droxy-benzyl and triazole rings inclined at an angle of only 3.2 (7)°. In the crystal, O-H⋯N hydrogen bonds between the hy-droxy group and the triazole ring in concert with weak N-H⋯S inter-molecular inter-actions between the triazole ring and thione group form chains along [-210] enclosing R 2 (2)(8) graph-set motifs. A weak intra-molecular C-H⋯S inter-action and inter-molecular π-π inter-actions [centroid-centroid distance = 3.5990 (15) Å] are also observed.
