The title Schiff base, C13H13NO2S, adopts the phenol–imine tautomeric form and reveals an intramolecular O—HN hydrogen bond involving the hydroxy group and the imino N atom, forming an S(6) ring. The molecule is highly twisted with respect to the central imine group, which is reflected in the dihedral angle of 67.83 (10)° formed by the thienyl and phenol rings. The crystal packing is characterized by weak C—HO and C—Hπ interactions.
