In the title compound, C(15)H(15)N(3)S, the almost planar 2-benzyl-idenehydrazinecarbothio-amide unit (r.m.s. deviation = 0.0351 Å) is aligned at a dihedral angle of 64.42 (6)° with respect to the plane of the tolyl ring. The mol-ecule exhibits an E configuration for the azomethine linkage. In the crystal, inter-molecular N-H⋯S hydrogen bonds about centers of inversion lead to the formation of dimers.
