The title compound, C15H10BrFO, is isostructural with (2E)-1-(4-chlorophenyl)-3-(4-fluorophenyl)prop-2-en-1-one [Qiu et al. (2006 ▶). Acta Cryst. E62, o3525–o3526], but the structures of other dihalogen analogues, without fluorine, are different, although they are also isostructural within the series. The molecule is approximately flat, the dihedral angle between the ring planes being 8.49 (13)°. In the crystal structure, intermolecular C—H⋯O, C—H⋯F and C—H⋯Br hydrogen bonds link molecules into V-shaped ribbons running parallel to  and stacked with an interplanar distance of approximately 3.53 Å (centroid–vcentroid distance = 3.857 Å)..
