California State Prison Corcoran opened in 1988 to address the state's growing need for maximum security bed space during a period of rapid prison population expansion. The facility was constructed in the agricultural community of Corcoran in Kings County, joining what would become a complex of correctional facilities in the area. Throughout its history, Corcoran has experienced notable incidents including investigations into staff conduct and inmate treatment during the 1990s that led to reforms in CDCR policies. The prison's Security Housing Unit became one of California's primary supermax facilities for the state's most dangerous offenders. Today, California State Prison Corcoran continues serving as a critical component of California's maximum security corrections infrastructure, housing serious violent offenders while implementing modern correctional standards and oversight.

Corcoran is home to a number of high-profile inmates including: Charles Manson, Juan Corona, Phillip Garrido, Rodney Alcala, and Charles Andrew Williams.
