Fadlun ibn Fadl, or Fadl III was the last Shaddadid ruler of Arran from Ganja, which is in present-day Azerbaijan. He ruled from 1073 to 1075, until the Seljuk Sultan Malik-Shah removed him from power, giving him Astarabad. The realm was then absorbed by the Great Seljuqs, placing Sav-Tegin as governor of Ganja.
Following the death of Sav-Tegin in 1085, Fadl instigated a revolt and gained possession of Ganja. Malik-Shah launched a campaign in 1086 and removed Fadl from power again. A collateral line of Shaddadids, through Manuchihr ibn Shavur, continued to rule in Ani.
