Sir Abdullah bin Khalifa Al-Busaidi, , (13 February 1911 – 1 July 1963) (), was the 10th Sultan of Zanzibar after the death of his father, Sir 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 during a period of rising African nationalism. In addition, by the time of his death, both his legs had been amputated due to disease.
He ruled Zanzibar from 9 October 1960 to 1 July 1963. On his death, he was succeeded as Sultan by his son Jamshid, who was deposed during the Zanzibar Revolution in January 1964.
