The Wanyan (; Manchu: Wanggiya; Jurchen script: ) clan was among of the clans of the Heishui Mohe tribe living in the drainage region of the Heilong River during the time of the Liao dynasty, which was ruled by the Khitan. Of the Heishui Mohe, the clan was counted by the Liao among the "uncivilized Jurchen" (生女真) indicating that the clan was not subject to the direct rule of the Khitan Emperors. Those Heishui Mohe clans ruled by the Liao dynasty/Khitan Empire were referred to as "civilized Jurchen" (熟女真).
