In the title compound, C16H22ClNS, the nine-membered 2,3-dihydro-1,3-benzothia­zole ring system is essentially planar, with a maximum deviation of 0.025 (2) Å for the N atom. Its plane is almost perpendicular to the main plane of the substituted cyclo­hexane ring, which adopts a chair conformation. In the crystal, the molecules are linked by C—H⋯π inter­actions.
