The title mol­ecule, C18H18N2OS, exists as an L-shaped structure with the mean plane of the 4-methyl­phenyl group twisted slightly about the mean plane of the pyrazole-1-carbaldehyde group by 4.7 (2)°, which in turn makes an angle of 82.4 (7)° with the mean plane of the thio­phenyl group. The S-methyl group is slightly twisted out of plane, probably due to steric repulsion between the methyl H and the phenyl H atoms. The crystal packing is stabilized by inter­molecular C—H⋯O hydrogen bonding between a thio­phenyl H atom and the carbaldehyde O atom, which links the mol­ecules into chains in an alternate inverted pattern parallel oblique to the bc face and along the a axis of the unit cell.
