An analysis of the effects associated with the Kaluza-Klein excitations of the photon and of the W and Z bosons on g_\ensuremathμ\ensuremath-2 for d number of extra dimensions with large radius compactifications is given. The Kaluza-Klein effects on g_\ensuremathμ\ensuremath-2 are found to be very sensitive to the number of extra dimensions. For models where the quark-lepton generations live on the four-dimensional wall, it is shown that when the constraints from the Kaluza-Klein corrections to the Fermi constant are included, the effects of the Kaluza-Klein excitations to g_\ensuremathμ\ensuremath-2 become too small to be observable. A model which evades Kaluza-Klein corrections to the muon decay \stackrel\ensuremath→\ensuremathμe\ensuremathνe\ensuremathν_\ensuremathμ without suppression of their effects on g_\ensuremathμ\ensuremath-2 is discussed.
