Suade Hümeyra Hanımsultan (Ottoman Turkish: سعاده حمیرہ خانم سلطان, "good luck" and "red"; also Hümeyra Özbaş; 4 June 1917 – 17 May 2000) was an Ottoman princess, the daughter of Fatma Ulviye Sultan, daughter of Mehmed VI and Nazikeda Kadın, and her first husband Damat Ismail Hakkı Pasha.

[1] She was the only child of Ulviye Sultan, daughter of Sultan Mehmed VI[1] and Nazikeda Kadın,[2] and Damat Ismail Hakkı Pasha, son of the last grand vizier Ahmet Tevfik Pasha[1] and Elisabeth Tschumi.

[5] In 1939, a special law was passed for the return to Turkey of the three children of Enver Pasha, and the daughter of his wife Naciye Sultan from her second marriage.

As Hümeyra's father had taken part in the War of Independence, she was also allowed to return to her country under the same law.

[5] She then taught Turkish at the Princeton University, where she met her future husband, Halil Özbaş.
