In the title compound, C(10)H(5)FO(3), the chromenone ring is essentially planar, with a maximum deviation of 0.039 (1) Å. The dihedral angle between the fluoro-subsituted benzene ring and the pyran ring is 1.92 (4)°. In the crystal, mol-ecules are connected via weak inter-molecular C-H⋯O hydrogen bonds, forming supra-molecular ribbons along the b axis. These ribbons are stacked down the a axis.
