The Wisconsin Secure Program Facility (WSPF), originally the Supermax Correctional Institution, is a Wisconsin Department of Corrections prison for men, located in Boscobel, Wisconsin, US. The facility is located east of central Boscobel, off of Wisconsin Highway 133.
The prison has a capacity of 500. As of November 2022, the population is 372.
In November 1999, the WSPF opened as the Supermax Correctional Institution on a 24-acre (9.7 ha) site.
In October 2003, the prison was renamed to the Wisconsin Secure Program Facility.
In 2009, the Associated Press filed a lawsuit against the Wisconsin Department of Corrections (WIDOC), trying to force the agency to release a video of an explosion of a stinger grenade launched into a prisoner's cell. The video was eventually released, the AP was awarded legal fees, and the inmate settled an excessive force lawsuit with WIDOC for US$49,000 (equivalent to $73,534 in 2025).
