Ali Bey Mihaloğlu or Gazı Alauddin Ali Bey Mihaloğlu, (1425—1507) was an Ottoman military commander in 15th century and the first sanjakbey of the Sanjak of Smederevo. He was one of the descendants of Köse Mihal, a Byzantine governor of Chirmenkia and battle companion of Osman Gazi. Some historians believed that the epic figure of Alija Đerđelez was inspired by Ali Bey Mihaloglu. In 1459 he raided Transylvania, province of Hungary but was beaten by the Transylvanian voivode, uncle of King Matthias and former Regent of Hungary Michael Szilágyi at Futak, and thus was forced to retreat.
