The Pindaris were irregular military plunderers and foragers in 17th- through early 19th-century Indian subcontinent who accompanied initially the Mughal army, later the Maratha army, and finally on their own before being eliminated in the 1817–19 Pindari War. They were unpaid and their compensation was entirely the loot they plundered during wars and raids. They were mostly horsemen armed with spears and swords who would create chaos and deliver intelligence about the enemy positions to benefit the army they accompanied. The majority of their leaders were Muslims, but also had people of all classes and religions.

The earliest mention of them is found in the Mughal period during Aurangzeb's campaign in the Deccan, but their role expanded with the Maratha armed campaigns against the Mughal empire. They were highly effective against the enemies given their rapid and chaotic thrust into enemy territories, but also caused serious abuses against allies such as during the Pindari raid on Sringeri Sharada Peetham in 1791. By the early 1800s, armed Pindari militia groups sought wealth for their leaders and themselves. There were an estimated 20,000 to 30,000 Pindari militia during the "Gardi-ka-wakt" ("period of unrest") in north-central India around 1800–1815 CE, who looted villages, captured people as slaves for sale, and challenged the authority of local Muslim sultanates, Hindu kingdoms, and the British colonies.

Francis Rawdon-Hastings, the Governor-General of British India, led an 120,000 strong force in early 19th-century against the Pindaris during the Third Anglo-Maratha War; the campaign became known as the Pindari War.
