In the mol-ecule of the title compound, C(18)H(14)O(3), there is an intra-molecular O-H⋯O=C hydrogen bond between the carbonyl and hy-droxy groups on the naphthalene ring system. The angles between the C=O bond vector and the least-squares planes of the naphthalene ring system and the phenyl ring are 30.58 (6) and 42.82 (7)°, respectively, while the dihedral angle between the naphthalene ring system and the phenyl ring is 58.65 (5)°. In the crystal, mol-ecules are connected by pairs of inter-molecular O-H⋯O=C hydrogen bonds, forming centrosymmetric dimers.
