Saray Mulk Khanum (Chagatai: سرای ملک خانم; c. 1341 – 1408) was a senior consort of the Timurid Empire as the chief consort of Timur, also known as Tamerlane the Great, the founder of the Timurid Empire as well as the Timurid dynasty.
By birth, she was a princess of Moghulistan as a daughter of Qazan Khan ibn Yasaur and was also a direct descendant of Genghis Khan.
The Timurid dynasty, self-designated as Gurkani, was the ruling dynasty of the Timurid Empire (1370–1507). It was a Sunni Muslim dynasty or Barlās clan of Turco-Mongol origin descended from the warlord Timur (also known as Tamerlane). The word "Gurkani" derives from Gurkân (گورکان)—a Persianized form of the Mongolian word kürgen, meaning 'son-in-law'. This was an honorific title used by the dynasty as the Timurids were in-laws of the line of Genghis Khan, founder of the Mongol Empire, as Timur had married Saray Mulk Khanum, a direct descendant of Genghis Khan. Members of the Timurid dynasty signaled the Timurid Renaissance, and they were strongly influenced by Persian culture and established two significant empires in history, the Timurid Empire (1370–1507) based in Persia and Central Asia, and the Mughal Empire (1526–1857) based in the Indian subcontinent.
