In the title compound, C15H19NO4, the cyclohexyl ring adopts a chair conformation with both exocyclic C—C bonds in equatorial orientations. The dihedral angle between the basal plane of cyclohexyl ring and the 2,4-dihydroxybenzaldehyde moiety is 84.13 (13)°. An intramolecular O—H⋯N hydrogen bonds closes an S(6) ring. In the crystal, Oc—H⋯Op (c = carboxylic acid, p = phenol) hydrogen bonds link the molecules into [100] C(13) chains whereas an Op—H⋯Oc hydrogen bond generates [101] C(15) chains. Together, these bonds generate (010) sheets incorporating R
2
2(20) loops. Weak C—H⋯O and C—H⋯π interactions also occur.
