Mir Habib Isfahani (Persian: میر حبیب اصفهانی) was a warlord who used to be in the employment of the Mughal Subedars (officers) of Bengal, but after being discontent with promotions, went on to aid the Maratha invaders of Bengal and aided in the various Maratha campaigns carried out in Bengal, Bihar, Orissa and adjoining places.
Mir Habib Isfahani was a Shia Muslim, soldier-turned-commander, in the employment of Alivardi Khan.
In 1742 when the Maratha invaders under Roghuji Bhosla and his prime minister Bhaskar Pandit invaded the Bengal Subah, Mir Habib Isfahani was lured to join their forces in search of loots as he was not content with his salary as a commander of Nawab Alivardi Khan's army.
In 1748, Mir Habib joined forces with Maratha general Raghoji I Bhonsle to invade Bengal, also with the support of Mustafa Khan, an Afghan defect from the Nawab's army.
