Florida State Prison (FSP), otherwise known as Raiford Prison, is a correctional institution located in unincorporated Bradford County, Florida,[1] with a Raiford postal address.

The facility, a part of the Florida Department of Corrections, is located on State Road 16 right across the border from Union County.

With a maximum population of over 1,400 inmates, FSP is one of the largest prisons in the state.

Union Correctional Institution also houses male death row inmates while Lowell Annex houses female death row inmates.

Even though Union Correctional Institution is on the same property, immediately north-west of FSP, the county line (with Union County) runs in between the two, which makes Raiford the United States Postal Service address city of Union Correctional Institution, while Starke is the USPS address city of Florida State Prison.
