The Old Atlanta Prison Farm is an abandoned, city-owned prison complex in southwest DeKalb County in the U.S. state of Georgia. From approximately 1920 to 1990, the farm was worked by prisoners to produce food for the region's prison system. There are limited historical records detailing the operation of the farm, especially after 1965.

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.
