  This paper deals with the steady-state polytropic fluid accretion onto a
higher-dimensional Reissner-Nordstr$\ddot{o}$m black hole. We formulate the
generalized mass flux conservation equation, energy flux conservation and
relativistic Bernoulli equation to discuss the accretion process. The critical
accretion is investigated by finding critical radius, critical sound velocity
and critical flow velocity. We also explore gas compression and temperature
profiles to analyze the asymptotic behavior. It is found that the results for
Schwarzschild black hole are recovered when $q=0$ in four dimensions. We
conclude that accretion process in higher dimensions becomes slower in the
presence of charge.
