Jan bin Jan (Arabic: جان بن جان), Jinn bin Jann or Gian bin Gian, was the king of the jinn and was the last of the seventy-two jinn of Sulaiman. He is the ruler of Jinnestan with command over all of his kind. Builder of the great pyramids of Misr, his shield was a powerful magical item that came into the hands of Prophet Sulaiman, allowing him to bind jinn.
He was overthrown by Azazil. It was said he had been the governor of the world for the two thousand years before the creation of Adam.
It was the buckler of Jann bin Jann that the Persian king Tahmuras took with him to Jinnistan, when he went to fight the deevs.
