In the cation of the title organic ion pair compound, C 23 H 20 ClN 2 O 3   + ·CH 3 O − , the cyclo­hexyl ring shows a half-boat conformation and the dihedral angles between two benzene rings and the pyran ring are 83.14 (7) and 73.18 (9)°. In the crystal, centrosymmetrically related cations are linked into a dimer by pairs of N—H⋯N hydrogen bonds, generating an  R   2   2 (12) ring motif. The anion inter­acts with the dimer through an N—H⋯O hydrogen bond. π–π inter­actions between pyran rings of adjacent dimers, with a centroid–centroid distance of 3.861 (2) Å, are also observed.
