In the title compound, C 19 H 16 O, the pyran ring is in a half-chair conformation. The essentially planar naphthalene ring system (r.m.s. deviation = 0.020 Å) forms a dihedral angle of 14.37 (5)° with the fused benzene ring. In the crystal, pairs of molecules are connected into inversion dimers by weak C—H...O hydrogen bonds to generate R 2 2 (6) loops.
