The Trump administration has formally requested $152 million in its fiscal year 2027 budget proposal to rebuild Alcatraz Island's shuttered federal penitentiary and reopen it as an active prison. The facility, located in San Francisco Bay, was decommissioned in 1963 after federal officials determined it was too costly to operate relative to mainland prisons. It has since become one of the most visited national park sites in the United States.

The funding request is embedded within a larger budget proposal that would increase defense spending while reducing nondefense discretionary spending by approximately $73 billion. The Alcatraz line item is among the more unusual allocations in the blueprint, reviving a facility that has been out of federal corrections use for more than six decades.

The administration has not detailed what inmate population would be housed at a rebuilt Alcatraz, nor has it outlined a timeline for construction or a projected operational capacity. The island's infrastructure would require substantial renovation, as the existing structures have deteriorated significantly since closure and have been maintained primarily for their historical and tourist value.

The proposal faces an uncertain path in Congress, where budget priorities must be negotiated before any funds can be appropriated. Critics have raised questions about the practical and financial logic of rebuilding a remote island prison when mainland federal facilities already face overcrowding and staffing challenges. Supporters of a tougher-on-crime posture have framed the proposal as consistent with the administration's broader push to expand federal detention capacity.
