American Prison: A Reporter's Undercover Journey into the Business of Punishment is a 2018 book by Shane Bauer, published by Penguin Press, about incarceration in the United States and the usage of private prisons.

Bauer had worked at the Winn Correctional Center in Winn Parish, Louisiana, then operated by Corrections Corporation of America (now CoreCivic), as an undercover journalist in 2014.
