Hakeem Shaikh Ilam-ud-din Ansari (died 1641),[1] known by his royal title Wazir Khan, was a Mughal administrator who was the Subahdar of Subah of Lahore during 1631–1639.

He was also appointed twice the governor of Agra Subah and held the office of Grand Vizier for a brief period after the accession of Shah Jahan in 1627/1628.

His adeptness in medical practice, coupled with a discerning comprehension of the temperament of the Prince, led to his appointment as Superintendent of the Camp Court, a position he earned graciously.

During the Prince's stay at Junair, Wazir Khan ascended to the prestigious position of the Divan, marking a significant elevation in his status.

His benevolent actions extended to infrastructure development, as he constructed roads, streets, shops, mosques, rest-houses, a school, a hospital, and wells for public use, alleviating the burdens of everyday life for the citizens.

Described as a man of quiet demeanor and steadfast temperament, he led a modest existence, eschewing extravagance in both personal and domestic matters.
