"Öküz" Mehmed Pasha ("Mehmed Pasha the Ox"; died 23 December 1619), also known as Kara Mehmed Pasha ("the Black") or "Kul Kıran" Mehmed Pasha ("the Slavebreaker"), was an Ottoman statesman, administrator and military figure of the early 17th century who held the office of Grand Vizier twice, the first time from 17 October 1614 to 17 November 1616 (during the reign of Ahmed I) and the second time from 18 January 1619 to 23 December 1619 (during the reign of Osman II the Young). He was also governor of Egypt from 1607 to 1611. Okuz Mehmed's nickname "Kul Kiran" (slavebreaker) came from his success in crushing the mutiny in Egypt during the early 1600s (soldiers were often known as kul or slave).
