Al-Sultan al-Azam Ghiyath al-Dunya Wal Din Abu'l Muzaffar Balban al-Sultan (Persian: السلطان الاعظم غیاث الدنیا والدین ابوالمظفر بلبن السلطان; 1216 – 13 January 1287), more famously known as Ghiyath al-Din Balban or simply Balban, was the ninth Mamluk sultan of Delhi. He had been the regent of the last Shamsi sultan, Mahmud until the latter's death in 1266, following which, he declared himself sultan of Delhi.
His original name was Baha-ud-Din. He was an Ilbari Turk. When he was young he was captured by the Mongols, taken to Ghazni and sold to Khawaja Jamal-ud-din of Basra, a Sufi. The latter then brought him to Delhi in 1232 along with other slaves, and all of them were purchased by Iltutmish. Balban belonged to the famous group of 40 Turkic slaves of Iltutmish.
