  We investigate the dependence of the $\rho$ meson-nucleon coupling constant
on the temperature of the medium, using the soft-wall model of AdS/QCD. The
finite temperature profile functions for the vector and fermion fields were
applied in the model having thermal dilaton field. The interaction Lagrangian
in the bulk between these fields was written as in zero temperature case and
includes minimal and magnetic type interactions. Temperature dependence of the
$g_{\rho NN}(T)$ coupling constant and its terms are plotted. We observe that
the coupling constant and its separate terms become zero at the medium
temperature near the Hawking temperature of phase transition.
