Qutb al-Din Aibak (r. c. 1206–1210) was a general of the Ghurid king Mu'izz ad-Din Muhammad Ghori. He was in-charge of the Ghurid territories in northern India, and after Mu'izz ad-Din's death, he became the ruler of an independent kingdom that evolved into the Delhi Sultanate ruled by the Mamluk dynasty.

A native of Turkestan, Aibak was sold into slavery as a child. He was purchased by a Qazi at Nishapur in Persia, where he learned archery and horse-riding among other skills. He was subsequently resold to Mu'izz ad-Din in Ghazni, where he rose to the position of the officer of the royal stables.

 During the Khwarazmian-Ghurid wars, he was captured by the scouts of Sultan Shah; after the Ghurid victory, he was released and highly favoured by Mu'izz ad-Din.After the Ghurid victory in the Second Battle of Tarain in 1192, Mu'izz ad-Din made Aibak in-charge of his Indian territories. Aibak expanded the Ghurid power in northern India by conquering and raiding several places in the Chahama etc.
