In the title compound, C17H15N3OS, the phenothia­zine ring system is slightly bent, with a dihedral angle of 13.68 (7)° between the benzene rings. The dihedral angle between the oxadiazole ring and the adjacent benzene ring is 7.72 (7)°. In the crystal, a π–π inter­action with a centroid–centroid distance of 3.752 (2) Å is observed between the benzene rings of neighbouring mol­ecules.
