  In this work, we present a gravitational dual of a Josephson junction
constructed from the AdS/BCFT correspondence. On the gravity side, we consider
a planar AdS-Schwarzschild black hole. Our junction is connected by the
boundary $Q$ with tension $\Sigma$ of the boundary CFT. Our computations on the
gravity side reproduce the standard relation between the current across the
junction and the phase difference of the condensate controlled by the tension
$\Sigma$. We also study the maximum current's dependence on the junction's
tension and size and reproduce familiar results.
