We study the impact of an additional U (1) ^' gauge symmetry with flavor-dependent charges for quarks and leptons on the LHC flavor anomalies observed in BK^*^+^-, R (K) =B^+^-/Be^+e^-, and h. In its minimal version with two scalar doublets, the resulting model naturally explains the deviations from the Standard Model observed in BK^*^+^- and R (K). The CMS access in h can be explained by introducing a third scalar doublet, which gives rise to a prediction for 3. We investigate constraints from flavor observables and direct LHC searches for ppZ^'^+^-. Our model successfully generates the measured fermion-mixing matrices and does not require vectorlike fermions, unlike previous attempts to explain these anomalies.
