Sufi Khalil Beg Mawsilu

Sufi Khalil Beg Mawsilu (died 1491) was a Turkoman military officer from the Mawsillu clan, who served the Aq Qoyunlu. He was one of the leading figures during the reign of Sultan Ya'qub Beg (r. 1478–1490), and played a pivotal role in the succession struggle that took place after the latter's death. He put Ya'qub's eldest son Baysunghur (who was then nine-years-old) on the throne, ruling as the virtual ruler of the realm until he was defeated and killed by his rival, Sulayman Beg Bijan.
