Abu al-Hasan 'Ali (died c. 1009) was ruler of Khwarazm from 997 until his death. The second member of the Ma'munid dynasty, he was the son of Ma'mun I ibn Muhammad.

In 997 Ali took over Khwarazm following his father's death. Little is known of his reign, but his emirate was dependent upon the Karakhanids, rivals of the Ghaznavids.[1] He died sometime around 1009 and was succeeded by his brother, Abu al-Abbas Ma'mun.
