Toktar Ongarbayuly Aubakirov (Kazakh: Тоқтар Оңғарбайұлы Әубәкіров (Toqtar Oñğarbaiūly Äubäkırov), Russian: Токтар Онгарбаевич Аубакиров, born on 27 July 1946) is a retired Kazakh Air Force officer and a former cosmonaut.

[1] Toktar Aubakirov was born in Karkaraly District, Karaganda Region, Kazakh SSR, which is now Kazakhstan.

Between 1976 and 1991 Aubakirov served as a test pilot at the Mikoyan Experimental Design Bureau (MiG aircraft).

On 2 October 1991 he launched with Russian cosmonaut Alexander Volkov as flight commander, and the Austrian research cosmonaut Franz Viehböck in Soyuz TM-13 from the Baikonur Cosmodrome spaceport, and spent over eight days in space.

Their mission was the last launched by the Soviet Union, which dissolved shortly thereafter, with Aubakirov becoming a citizen of the independent Republic of Kazakhstan.
