Qasim ad-Dawla Abu Said Aq Sunqur al-Hajib (also Aksunkur el-Hacib or Aksungur al-Hajib) was the Seljuk governor of Aleppo under Sultan Malik Shah I. He probably enjoyed some independence from his lord and was from 1087 the de-facto ruler of most of Syria. In 1094 Tutush I, the ruler of Damascus, accused Aq Sunqur of treason and had him beheaded.
Aq Sunqur al-Hajib was the father of Zengi, the founder of the Zengid dynasty.
