In the title compound, C(19)H(15)FO(3), the dihedral angle between the naphthalene ring system and the benzene ring is 62.93 (5)°. The bridging carbonyl C-C(=O)-C plane makes dihedral angles of 45.55 (6) and 28.62 (7)°, respectively, with the naphthalene ring system and the benzene ring. Weak inter-molecular C-H⋯O hydrogen bonds and C-H⋯π inter-actions stabilize the crystal packing.
