Abbas III (January 1732 – February 1740) (Persian: شاه عباس سوم‎‎) reigned 1732–1736; was a son of Shah Tahmasp II and Shahpuri Begum of the Safavid dynasty. After the deposition of his father by Nader Khan (the future Nader Shah) the infant Abbas was appointed nominal ruler of Iran on 7 September 1732. Nader Khan, who was the real ruler of the country, assumed the positions of deputy of state and viceroy. Abbas III was deposed in March 1736, when Nader Khan had himself crowned as Nader Shah.
