Bayezid II or Sultân Bayezid-î Velî (3 December 1447 – 26 May 1512) (Ottoman Turkish: بايزيد ثانى Bāyezīd-i sānī, Turkish:II. Bayezid or II. Beyazıt) was the eldest son and successor of Mehmed II, ruling as Sultan of the Ottoman Empire from 1481 to 1512. During his reign, Bayezid II consolidated the Ottoman Empire and thwarted a Safavid rebellion soon before abdicating his throne to his son, Selim I. He is most notable for evacuating Jews from Spain after the proclamation of the Alhambra Decree and resettling them throughout the Ottoman Empire.

Bayezid II was the son of Mehmed II (1432–81) and Emine Gülbahar Hatun.

Bayezid II married Gülbahar Hatun, who was the mother of Bayezid II's successor, Selim I and nephew of Sitti Mükrime Hatun.

Bayezid II's overriding concern was the quarrel with his brother Cem, who claimed the throne and sought military backing from the Mamluks in Egypt. Having been defeated by his brother's armies, Cem sought protection from the Knights of St. John in Rhodes. Eventually, the Knights handed Cem over to Pope Innocent VIII (1484–1492). The Pope thought of using Cem as a tool to drive the Turks out of Europe, but as the papal crusade failed to come to fruition, Cem was left to languish and die in a Neapolitan prison. Bayezid II paid both the Knights Hospitaller and the pope to keep his brother prisoner.
