We construct a holographic model for the superconductor-insulator-superconductor (SIS) Josephson junction at zero temperature by considering a complex scalar field coupled with a U(1) gauge field in the four dimensional Anti de Sitter soliton background. As a result, we successfully reproduce many characteristic features of the Josephson junction in condensed matter physics, such as the sine relation between the DC current and the phase difference across the junction.
