  We propose an extension of the Standard Model (SM) for radiative neutrino
mass by introducing a dark $U(1)_D$ gauge symmetry. The kinetic mixing between
the SM gauges and the dark $U(1)_D$ gauge arises at 1-loop mediated by new
inert scalar fields. We show that the tiny neutrino mass and dark matter
candidates are naturally accommodated. Motivated by the recent measurement of
$(g-2)_{\mu}$ indicating $4.2~ \sigma$ deviation from the SM prediction, we
examine how the deviation $\Delta a_{\mu}$ can be explained in this model.
