Rukiye Sabiha Sultan (Ottoman Turkish: رقیہ صبیحه سلطان; "charm" and "morning" or "beautiful"; after 1952 Sabiha Osmanoğlu; 19 March 1894 – 26 August 1971) was an Ottoman princess, the third and last daughter of Sultan Mehmed VI and his first wife Nazikeda Kadın.

She was the first wife of Şehzade Ömer Faruk, son of Caliph Abdulmejid II and Şehsuvar Hanım.

Her mother was Nazikeda Kadın, daughter of Prince Hasan Ali Marshania and Princess Fatma Horecan Aredba and first wife of her father.

[8] Her first suitor is thought to be Rauf Orbay,[8] a relative of one of Sultan Abdul Hamid II's consorts, Sazkar Hanım.

[24] Later they moved to Nice, France, where her youngest daughter Hibetullah Necla Sultan was born on 16 May 1926, the same day of Mehmed VI's death.

[26] He then moved with his youngest daughter Fevziye Sultan in with his cousin Sabiha and Ömer Faruk, where he died in 1931.

[28] On 26 September 1940, she attended the wedding of her daughter, Neslişah Sultan and Prince Mohamed Abdel Moneim, son of Egypt's last khedive Abbas II Hilmi.

[5] Sabiha's husband, Ömer Faruk, developed an increased interest in his cousin Mihrişah Sultan, the daughter of crown prince Şehzade Yusuf Izzeddin.

[33] And so, on 5 March 1948, after twenty eight years of marriage, Ömer Faruk divorced Sabiha, and married Mihrişah Sultan.

[34] Following her divorce, Sabiha Sultan left her home in Maadi on the other side of Cairo to be closer to her eldest daughter, Princess Neslişah.

[37] But, as soon as the female members of the Ottoman family were allowed to return to Turkey in 1952, she moved to Istanbul, when she took the name Sabiha Osmanoğlu.

She rented a small flat in Kuyuku Bostan Street in the district of Nişantaşı, and the few things she still had in Egypt were sent to Istanbul.

[36] Sabiha Sultan died on 26 August 1971 at the age of seventy seven in her mansion in Çengelköy, Istanbul, and was buried in Aşiyan Asri Cemetery.
