The double ring-shaped Hulthn potential is proposed in this paper. By using the analytical method of function, the approximate analytical solutions of bound state solutions of Schrdinger equation for the double ring-shaped Hulthn potential are presented within the framework of an exponential approximation of the centrifugal potential for arbitrary l-states. The normalized angular and radial wave function expressed in terms of hypergeometric polynomials are presented. The energy spectrum equations are obtained. The wave function and the energy spectrum equations of the system are related to three quantum numbers and parameters of double ring-shaped Hulthn potential. The polar angular wave functions of the central potential and ring-shaped potential and the energy spectrum equations of Hulthn potential turn out to be the special cases of the double ring-shaped Hulthn potential.-
