Mahadaji Shinde (Marathi: ?????? ????? Mah?daj? ?i?d?) (Died: 12 February 1794) also spelled as Mahadji Scindia, was a Maratha ruler of the Maratha Empire is a state of Gwalior in central India. He was the fifth and the youngest son of Sardar Ranoji Rao Scindia.

Mahadaji was instrumental in resurrecting Maratha power in North India after the Third Battle of Panipat in 1761, and rose to become a trusted lieutenant of the Peshwa, leader of the Maratha Empire. Along with Madhavrao I and Nana Fadnavis, he was one of the three pillars of Maratha Resurrection. During his reign, Gwalior became the leading state in the Maratha Empire and one of the foremost military powers in India. After accompanying Shah Alam II in 1771 to Delhi, he restored the Mughals in Delhi, under the suzerainty of Marathas.

He annihilated the power of Jats of Mathura and during 1772-73 he destroyed the power of Pashtun Rohillas in Rohilkhand and captured Najibabad. His role during the First Anglo-Maratha War was greatest from the Maratha side since he humbled the British in Central India, single handed, which resulted in the Treaty of Salbai in 1782, where he mediated between the Peshwa and the British.
