The Louisiana State Penitentiary (LSP, also known as Angola, and nicknamed the "Alcatraz of the South" and "The Farm") is a maximum-security prison farm in Louisiana operated by the Louisiana Department of Public Safety & Corrections. It is named Angola after the country from which many of the enslaved Africans came who worked on the former plantation that occupied this territory.

It is the largest maximum-security prison in the United States with 6,300 prisoners and 1,800 staff, including corrections officers, janitors, maintenance, and wardens. It is located on an 18,000-acre (7,300 ha) property that was previously the Angola Plantations owned by Isaac Franklin in unincorporated West Feliciana Parish in the east of the state, directly adjacent to the Mississippi state line. The prison is located at the end of Louisiana Highway 66, around 22 miles (35 km) northwest of St. Francisville. Angola is bordered on three sides by the Mississippi River. Burl Cain served as the warden from 1995 to March 7, 2016. Death row for men and the state execution chamber for both sexes are located at the Angola facility.
