Mississippi State Penitentiary (MSP), also known as Parchman Farm, is a maximum-security prison farm located in the unincorporated community of Parchman in Sunflower County, Mississippi, in the Mississippi Delta region. Occupying about 28 square miles (73 km2) of land, Parchman is the only maximum security prison for men in the state of Mississippi, and is the state's oldest prison.

A prison farm is a large correctional facility where penal labor convicts are forced to work—legally or illegally—on a farm, usually for manual labor, largely in the open air, such as in agriculture, logging, quarrying, and mining. In the United States, such forced labor is made legal by the thirteenth amendment to the Constitution; however, some other parts of the world have made penal labor illegal. The concepts of prison farm and labor camp overlap, with the idea that the prisoners are forced to work. The historical equivalent on a very large scale was called a penal colony.
