We study the effects of extra dimension on the muon anomalous magnetic moment in the stabilized Randall-Sundrum scenario. The effects of the Kaluza-Klein states heavier than the cut-off scale expected to be of order Λπ are neglected. Contribution from the spin-2 Kaluza-Klein states dominates over that from the spin-0 radion. The recent BNL E821 results impose a strict constraint on the parameter space of the model: Λπ ≈ 0.4-2.1 TeV with k/MPl = 0.01-0.1. Small k/MPl is preferred if Λπ is TeV scale.
