Sayyid Sir Abdullah bin Khalifa Al-Said, KBE, CMG (February 12, 1910 – July 1, 1963) (Arabic: عبد الله بن خليفة) was the 10th Sultan of Zanzibar after the death of his father, Khalifa bin Harub, who died on 9 October 1960 at age eighty-one. He was less popular than his father and had a rough reign as Sultan, as at the time of his death both his legs were amputated.
He ruled Zanzibar from October 9, 1960 to July 1, 1963. On his death, he was succeeded as Sultan by his son Jamshid.
