  We study the contribution of a generic charged Higgs $(H^+)$ to the muon
anomalous magnetic moment $a_{\mu}$ with the SUSY soft breaking parameters. We
find out that the deviation between the experimental data and the predicted SM
value on $a_{\mu}$ can be explained by the two-loop charged Higgs diagrams even
with $m_{H^+}\sim 400 GeV$.
