Malik Bahauddin Tughril (r. 1195–1210), commonly known as Bahauddin Tughril or Baha al-Din Tughril was a senior Turkic slave of the Ghurid ruler Muhammad of Ghor who was in charge of the Bayana region in the present-day Indian state of Rajasthan. He was admitted into the slave-household of the Ghurids during early reign of Muhammad of Ghor and gradually emerged as one of his eminent slave lieutenant along with Qutb al-Din Aibak, playing a significant role in the Ghurid conquest of northern Indian plain.
After Muhammad of Ghor seized Bayana in 1195–96 to guard the southern flank of Delhi, he made Tughril the viceroy of Bayana. Under his administration, the region of Bayana briefly emerged as a cosmopolitan centre, encouraging considerable Muslim settlements from all over Khurasan. After Muhammad of Ghor's assassination on 15 March 1206, Tughril like other Ghurid mamluks was manumitted, thereby he announced himself as the "Sultan". He died in 1210, and afterwards, the territory was soon brought under by Illtutmish, although Tughril's family continued to exercise influence over the region of Bayana even half a century after his death.
