Zubayda Khatun (1056 – 1099) was a granddaughter of Dawud Chaghri Beg, wife and cousin of Malik-Shah I.
She married and influenced her cousin Malik-Shah I, giving birth to Berkyaruq in 1081 and a daughter, Gawhar Khatun.
After Berkyaruk suppressed the rebellion and killed his uncle, he wanted to bring his mother with him, although his vizier Mu'ayyid al-Mulk opposed this.
[2] Berkyaruq's brother Muhammad Tapar later rebelled and declared himself as Sultan, reappointing Mu'ayyid al-Mulk, who had Zubayda Khatun captured and killed.
[2] Zubayda Khatun is portrayed by Sezin Akbaşoğulları in the Turkish historical drama The Great Seljuks: Guardians of Justice.
