Iron Gate III or Đerdap III (Serbian: Ђердап III) is a planned pumped storage power station on the Danube in Serbia, near the village of Dobra in the Golubac municipality. It would be the third Iron Gate power station, after Iron Gate I in 1972 and Iron Gate II in 1985. Unlike the first two, which were joint projects of Yugoslavia and Romania, the Iron Gate III would lie entirely on Serbian territory.
