We study the effects of extra dimensions on the muon anomalous magnetic moment with brane fluctuation. Since the coupling is naturally suppressed if brane fluctuation is considered by exponential softening factor for heavier states, the contribution from the whole Kaluza-Klein graviton tower is shown to be finite. The recent BNL E821 result is accommodated with (D = 4 + δ)dimensional gravitational scale, MD, in the range of MD ≃ 1.0-5.1 TeV (δ = 2), and MD ≃ 1.0-8.0 TeV (δ = 6) with the brane tension parameter f = (4π2τ)1/4, in the range f = 1-10 TeV.
