The title compound, C~16~H~11~ClO~2~, is a synthetic flavonoid. The fused-ring system is almost planar, with a mean deviation from the least-squares plane of 0.0204 (2) Å. The dihedral angle between the chromene group and the chlorophenyl ring is 50.9 (6)°, due to unfavourable steric interactions wi
