Salinas Valley State Prison (SVSP) is a 300-acre (120 ha) California state prison located 5 miles (8 km) north of Soledad, in Monterey County, California, adjacent to the Correctional Training Facility (aka Soledad State Prison).

The surrounding housing units hold level-4 and level-3 inmates, the two highest security rankings.

The prison had a gymnasium which, due to the prison's over-crowding, at one time had been converted into a dormitory but due to inmate population reductions was shut down around 2008.

The prison also houses an inpatient mental health program, formerly operated under the auspices of the California Department of State Hospitals (Salinas Valley Psychiatric Inpatient Program) to accommodate the psychological needs of inmates.

As of July 31, 2022, SVSP was incarcerating people at 102.5% of its design capacity, with 2,941 occupants.
