Aaron ibn Sargado was a tenth century AD gaon (Jewish religious leader) in Pumbedita, Babylonia. He was a son of Joseph ha-Kohen. According to the chronicle of Sherira, Sargado officiated from 943 to 960; others declare he died in 942. He was successor to the gaon Hananiah, the father of Sherira. Four of Sargado's legal decisions on religious problems are preserved, and are printed in the collection, "Ḥemdah Genuza," Nos. 37-40. One of these, it appears, was the answer to an inquiry from Kairwan.
