Sayf al-Din Qutuz, also romanized as Kutuz or Kotuz and fully al-Malik al-Muẓaffar Sayf ad-Dīn Quṭuz, was the Mamluk Sultan of Egypt. He reigned as Sultan for less than a year, from 1259 until his assassination in 1260, but served as the de facto ruler for two decades.

Mamluk or Mamaluk were non-Arab, ethnically diverse enslaved mercenaries, slave-soldiers, and freed slaves who were assigned high-ranking military and administrative duties, serving the ruling Arab and Ottoman dynasties in the Muslim world.
