Nawab Hafiz Sir Muhammad Ibrahim Ali Khan Bahadur(8 November 1849 – 23 June 1930) was the Nawab of Tonk from 1867 until his death in 1930.
He ascended the throne of Tonk following the deposition of his father by the British, who was charged guilty of mass murder. He attended all the three Delhi Durbars. In 1901, he passed a law for the conservation of wildlife and the environment in his state. This was also the first law enacted in present day Rajasthan for such a purpose.

In 1864, Ibrahim Ali Khan started a practise of sacrificing camels on Eid al-Adha. The family discontinued the practise in 2014, after Rajasthan declared the camel as a state animal.
Ibrahim Ali Khan's father Muhammad Ali Khan was found guilty in the mass-killings of the Thakur of Lawa state and his relatives. As a result, he was deposed by the British and exiled to Varanasi with an yearly pension of ₹60,000 (US$840). Subsequently, Ibrahim Ali Khan ascended the throne of Tonk on 20 December 1867 at the age of 20. As a punishment, his gun salute was reduced to 17 from 21.
