Muhammad Ahmad Khan Bahadur Ghalib Jang (Persian: احمد خان بنغاخ) or Ahmad Khan Bangash (Persian: احمد خان بنگش) was a Mughal nobleman and Nawab of Farrukhabad from the Rohilla Afghan Bangash dynasty.

His father Muhammad Khan Bangash was a powerful Mughal nobleman who ruled a large domain in what is now Uttar Pradesh, with his capital at Farrukhabad.

During the reign of his elder brother, Nawab Kaim Khan, he lived at the imperial Mughal capital of Delhi for some time.

[10] However, instead of paying the revenue from his lands he spent it on a silver howdah, a privilege which only Nawab Kaim Khan owned.

Ahmad Khan escaped to Delhi, where he placed himself under the protection of the Mughal nobleman Ghazi ud-Din Feroze Jung.

Disdaining to leave the place alive, Ahmad Khan practised the act of Utara or dismounting and had his soldiers tie their skirts of their heavy plaited coats (Jamaah) to fight to the death, cursing his men: "Have you brought me here only to see you run away".

[15] At the Battle of Khudaganj on the night of 12 August 1750, Ahmad Khan's troops surprised Nawal Rai, the deputy of Safdar Jang and gained victory.

[10][16] After a string of defeats, Ahmad Khan fled to the north and was only able to return after promising half of his lands to the Marathas in 1752.

[8] In 1757, Ahmad Khan Bangash readily contributed valuable troops to the attack of Awadh under Nawab Shuja-ud-Daula by Imad-ul-Mulk.

[12] Taking advantage of the Maratha threat to his power, Nawab Shuja-ud-Daula, the ruler of Awadh, attacked Farrukhabad in 1762.

[10] The celebrated Urdu poets, Mirza Sauda and Mir Soz were in the employ of Ahmad Khan Bangash.
