Little Crow's War is the name of an attack by a band of Dakota Sioux, led by Little Crow, against the agency in charge of their reservation and white settlers in the surrounding area.

Little Crow's War took place in August 1862.

The Dakota Sioux had been given inferior farm land by the government, which meant their crops failed. The government also failed to make agreed payments to the tribe, leaving them to starve.

700 white settlers and soldiers were killed by Little Crow's war band. As a result, the US Army sent soldiers to subdue the Sioux. 300 tribe members were sentenced to death, of whom 38 were hanged. The rest of the tribe was moved to the Crow Creek Reservation, where many starved. Any of them found outside the reservation were scalped for a bounty.
