In the title compound, C15H10Br2F2O, the dihedral angle between the two 3-fluoro-substituted benzene rings is 5.7 (5)°. The two bromine substituents on the chalcone moiety are close to anti as the Br-C-C-Br torsion angle is 176.9 (7)°. Weak C-Br interactions may contribute to the crystal stability.
