Bayezid Osman, also known as Osman Bayezid Osmanoğlu with a surname as required by the Republic of Turkey, or known by the Ottoman imperial name as Şehzade (Prince) Bayezid Effendi (Ottoman Turkish: بایزید عثمان; 23 June 1924 – 6 January 2017), was the 44th Head of the Imperial House of Osman, which ruled the Ottoman Empire from 1281 to 1922. The monarchy was abolished in 1922, with the modern Republic of Turkey replacing it.
He was the second son of Sultan Abdülmecid I's grandson Ibrahim Tevfik (24 September 1874 – 31 December 1931) by his fourth wife Hadice Sadiye Hanım. If the Ottoman monarchy were restored, he would have been Grand Sultan Bayezid III. He was a member of one of the younger branches of the House of Osman. He was the first member of the House of Osman to be born in exile, and the first head to have been born after the dissolution of the Ottoman Empire.
Osman never married and had no children. On 23 September 2009 with the death of Ertuğrul Osman, he succeeded to the head of the House of Osman. Osman's relative, Abdulhamid Kayıhan Osmanoğlu, announced on social media that Osman had died in New York on 6 January 2017, aged ninety-two.
