Muskegon Correctional Facility (MCF) is a prison of the Michigan Department of Corrections located in southeastern Muskegon, Michigan. The prison opened in 1974. Additional housing units opened since then to accommodate more prisoners. After the opening of additional state prisons in Pennsylvania was imminent, Pennsylvania withdrew its prisoners from MCF in 2011. Beginning in late April 2011, one group of about 240 prisoners was moved out of MCF each week. Wednesday, May 25, 2011 was the final day of operations, and the final "ride-out" of 239 Pennsylvania prisoners occurred on that day.
