Abu Mansur Wahsudan (also spelled Vahsudan; Persian: ابو منصور وهسودان) was the penultimate Rawadid amir (ruler) of Azarbaijan from 1025 to 1058/59. He is considered the most prominent ruler of his dynasty. With the assistance of his Kurdish neighbours, he initially contained the attacks of migrating Turkmen tribes, but was eventually forced to acknowledge the authority of the Seljuk ruler Tughril (r. 1037–1063) in 1054. He was succeeded by his son Abu Nasr Mamlan II (r. 1058/59–1070).
