Ali ibn Buya (Persian: علی بن بویه‎‎), known by his laqab (honorific epithet) Imad al-Dawla (c. 891/2 – December 949), was the founder of the Buyid dynasty in Iran (in Shiraz, 934–949).

Ali first entered the services of the Samanids under Nasr II, where he became a member of the ruler's entourage. From there he eventually joined Makan, who ruled Gorgan and Ray as a governor of the Samanids, in around 928. He may have done so at Nasr's suggestion; in any case, he managed to occupy a high position under Makan and gained army commissions for his two younger brothers, Hasan and Ahmad. In 930, however, Makan rebelled against the Samanids by seizing Khurasan; he was subsequently attacked by the Ziyarid prince Mardavij and forced to give up Tabaristan.

Ali and his brothers managed to defect to Mardavij's side just as the Ziyarid was preparing to undertake the conquest to the south of the Alborz mountains as far as Qazvin. Not long afterwards Mardavij granted Ali administrative rule over Karaj, a strategically important town probably situated near modern Bahramabad. While making a stop in Ray on his way to Karaj, however, Ali was warned by Mardavij's vizier al-'Amid that the Ziyarid was planning to eliminate him. Hurriedly leaving Ray, he arrived at and took over Karaj.

With a small number of Dailamite troops to support him, Ali sought to expand his position. Moving against the heretical Khurramites, who controlled the surrounding mountains, he gained control of the region and was heavily enriched by the expeditions. At the same time, he managed to maintain his troops' loyalty, despite Mardavij's attempts to incite them against their master.
