United States Penitentiary Leavenworth

USP Leavenworth currently houses approximately 1,807 adult male inmates, all of whom have been convicted of federal crimes. The facility operates at minimum to medium security levels, meaning it holds individuals who have been assessed as presenting lower escape risks and who generally have less violent institutional histories than those housed in high-security or administrative maximum facilities.

The federal inmate population at Leavenworth is diverse in terms of offense types. Residents include individuals convicted of drug trafficking, firearms offenses, financial crimes, immigration violations, and certain violent federal offenses. Because this is a federal institution, inmates come from across the United States — and sometimes from U.S. territories — rather than exclusively from Kansas or the surrounding region. As a result, families traveling to visit loved ones at USP Leavenworth may be coming from significant distances.

Inmate classification and housing assignments are determined through a formal BOP assessment process that considers factors such as offense severity, criminal history, institutional behavior, and program participation. Inmates may be reclassified over time as their circumstances change, which can occasionally result in transfers to other BOP facilities. Families who are unsure of a loved one's current location are encouraged to use the how to find an inmate guide on this site for step-by-step instructions on using the federal inmate locator and other search tools.

Inmates at USP Leavenworth reside in traditional cell-based housing units consistent with medium security federal penitentiary standards. Housing assignments are determined by a combination of security classification, program participation, behavior history, and available bed space. The facility's older architectural design means that housing units differ somewhat in layout from newer federal prisons, though all units meet BOP minimum standards for space, ventilation, and safety.

Incarcerated individuals receive three meals per day prepared in centralized kitchen facilities and served in accordance with federal nutritional guidelines. The BOP is required to accommodate medically necessary dietary needs, and religious dietary accommodations are also available in many cases.

Recreation is an important component of daily life at Leavenworth. Inmates have access to outdoor exercise yards, an indoor gymnasium, and organized sports and fitness activities when security conditions permit. The facility also offers leisure reading through its library services, and access to approved television and radio programming in common areas.

Medical, dental, and mental health services are provided on-site through a dedicated health services unit staffed by federally contracted medical professionals. Inmates with serious or chronic medical conditions may be referred to outside specialists or, in some cases, transferred to a federal medical center. The BOP maintains written standards for the delivery of health care across all federal facilities, and inmates have a formal process for submitting sick call requests and health care grievances.

USP Leavenworth offers a range of programs designed to support rehabilitation, reduce recidivism, and prepare inmates for successful reintegration into their communities upon release. Participation in programming can also positively affect an inmate's security classification and eligibility for certain BOP incentives, making it an important consideration for both inmates and their families.

Education programs include adult literacy instruction, GED preparation and testing, and continuing education courses. Inmates who lack a high school diploma or equivalent are strongly encouraged — and in some cases required — to participate in the literacy and GED programs as a condition of their sentence planning.

Vocational training opportunities provide inmates with hands-on skills in various trades, which can significantly improve employment prospects upon release. These programs vary by facility resources and availability, and eligible inmates are assigned through a formal enrollment process.

Substance abuse treatment is available through both residential and non-residential programming. The BOP's Non-Residential Drug Abuse Program (NDAP) and, where applicable, the Residential Drug Abuse Program (RDAP) address addiction issues through cognitive-behavioral approaches. Completion of RDAP may qualify eligible inmates for a sentence reduction under federal law, making it one of the most sought-after programs in the BOP system.

Religious and spiritual services are coordinated by on-site chaplaincy staff and accommodate a wide range of faith traditions. Religious programming includes worship services, study groups, and pastoral counseling. Inmates may also request religious items consistent with their documented faith and institution security guidelines.

Cognitive and life skills programs round out the programming offerings, addressing areas such as anger management, financial literacy, and pre-release planning. These programs help inmates develop the practical and emotional tools needed to reintegrate successfully after their sentences are complete.

Inmates at USP Leavenworth participate in work assignments that maintain facility operations and provide vocational experience. Inside job assignments include food service, maintenance, janitorial services, laundry operations, and clerical positions supporting administrative functions. Federal Prison Industries may operate programs at the facility where inmates produce goods or provide services while earning modest wages and developing workplace skills. Work assignments are considered part of an inmate's institutional responsibility and contribute to the orderly operation of the penitentiary. Job performance is evaluated and can influence security classification, program eligibility, and institutional reputation.

United States Penitentiary Leavenworth holds a unique and storied place in American correctional history. It was established in 1895 by an act of Congress and formally opened in 1903 as the first federal penitentiary to be purpose-built under the legislation that would eventually give rise to the Federal Bureau of Prisons. Before its construction, federal prisoners were housed in state facilities — an arrangement that proved increasingly inadequate as the scope of federal criminal law expanded in the late 19th century.

One of the most remarkable aspects of USP Leavenworth's construction is that inmates themselves played a central role in building the facility. Prisoners quarried and laid much of the stone used in the massive main building, contributing to what became one of the most architecturally striking correctional structures in the country. The defining feature of that architecture is the large central dome, which has become a symbol of the prison's enduring presence on the Kansas landscape.

Throughout its more than 120 years of continuous operation, Leavenworth has witnessed significant moments in American criminal justice history. The facility has seen notable escapes, institutional riots, and sweeping changes in corrections philosophy — from punitive hard-labor regimes in the early 20th century to the rehabilitation-focused models that emerged mid-century and the security-conscious approaches that define modern federal corrections. The prison played a particularly prominent role during the Prohibition era and World War II, when it held a diverse range of federal offenders including war resisters, bank robbers, and organized crime figures.

The facility has undergone numerous expansions and infrastructure upgrades over the decades while preserving much of its original historic character. Today, USP Leavenworth remains an active federal penitentiary and a living piece of American legal and correctional history, continuing to evolve while honoring more than a century of institutional tradition.

Over its 120-plus years of operation, USP Leavenworth has housed a number of high-profile federal inmates whose cases attracted significant national attention. A few of the most well-known figures connected to the facility include:

• Michael Vick — The former NFL quarterback and Pro Bowl player served time at Leavenworth after pleading guilty in 2007 to federal charges related to operating an illegal interstate dog fighting enterprise. His case drew widespread media coverage and sparked a national conversation about animal cruelty and athlete accountability.
• George "Machine Gun" Kelly — One of the most notorious gangsters of the Prohibition era, Kelly was convicted of kidnapping and spent years at Leavenworth. His colorful criminal career made him one of the defining figures of 1930s American organized crime. Curious about the records behind famous cases?

• Robert Stroud ("The Birdman of Alcatraz") — Before his famous transfer to Alcatraz, Stroud spent many years at Leavenworth, where he developed his well-known interest in ornithology and bird care. His story was later dramatized in the 1962 film starring Burt Lancaster.
• James Earl Ray — The convicted assassin of Dr. Martin Luther King Jr. was held at Leavenworth at various points during his incarceration, contributing to the facility's association with some of the most consequential criminal cases in American history.

The long roster of notable inmates at USP Leavenworth reflects both the breadth of federal criminal jurisdiction and the facility's historical role as one of the primary destinations for significant federal offenders over the past century.

Visitation at USP Leavenworth is an important way for families and loved ones to maintain meaningful connections with incarcerated individuals, and the Bureau of Prisons encourages regular visitation as part of a healthy reintegration process. However, visiting a federal facility requires advance preparation, and families should familiarize themselves with the approval process well before planning a trip.

Visitor approval: All prospective visitors must be approved in advance by submitting a visitor application to the institution. The inmate must first provide the names of individuals they wish to add to their approved visitor list, and each person on that list must then complete a background check process. Approval can take several weeks, so families should begin this process as early as possible. Visitors with certain criminal histories may be denied approval at the warden's discretion.

Identification requirements: All visitors age 16 and older must present a valid, government-issued photo ID upon arrival — such as a driver's license, state ID, or passport. Visitors who do not have valid identification will not be admitted.

Dress code: Federal facilities enforce strict dress code requirements. Visitors should avoid clothing that resembles inmate uniforms (typically khaki or olive green), clothing that is revealing or excessively tight, and any items that could conceal contraband. The institution reserves the right to deny entry to visitors whose clothing does not comply.

Visiting schedule: Visiting hours are set by the institution and may vary by housing unit, inmate status, and facility operational needs. Families are strongly encouraged to confirm current visiting schedules directly with the facility before traveling. You can review official visiting guidelines on the USP Leavenworth official BOP page.

During visits: Visitors may bring a limited amount of cash (typically in coin form or via an approved system) for vending machines in the visiting room. Children must be accompanied by an approved adult visitor at all times. Physical contact is generally limited to a brief hug and handshake at the beginning and end of visits. You may also wish to explore options to send money to an inmate through the BOP's approved financial services between visits.

Staying in contact with a loved one at USP Leavenworth is possible through several channels, each governed by specific federal Bureau of Prisons policies. Understanding the rules for each method helps ensure that correspondence and support reach your loved one without delays or rejections.

Mailing address: To send a letter or card, address your correspondence as follows:

• [Inmate Full Name, BOP Register Number]
• USP Leavenworth
• U.S. Penitentiary
• P.O. Box 1000
• Leavenworth, KS 66048

Always include the inmate's full legal name and BOP register number on all correspondence to ensure proper delivery. All incoming mail is inspected by institution staff in accordance with federal regulations. Certain items are prohibited, including those containing staples, glitter, stickers, or any substances that could potentially be used to introduce contraband.

Books and publications: Inmates may receive books, magazines, and newspapers only when sent directly from a publisher or approved vendor such as Amazon or Barnes &Noble. Packages sent from individuals — even family members — are generally not accepted and will be returned.

Phone calls: Inmates at USP Leavenworth may make outgoing phone calls through the BOP's approved telephone system. Family members must be on the inmate's approved call list and should expect calls to be monitored and recorded. Prepaid accounts can be set up through the BOP's contracted phone provider to receive calls.

Email: The BOP's CorrLinks system allows inmates to exchange electronic messages with approved contacts. Family members can register for a CorrLinks account online to receive and send messages once the inmate initiates the connection from their end.
