The Federal Correctional Institution, Danbury (FCI Danbury) is a low-security United States federal prison for male and female inmates in Danbury, Connecticut. It is operated by the Federal Bureau of Prisons, a division of the United States Department of Justice. The facility also has an adjacent satellite prison camp that houses minimum-security female offenders.

FCI Danbury was opened in August 1940 with the purpose of housing male and female inmates.^[1] It housed several high-profile political prisoners during World War II. Conscientious objectors, including poet Robert Lowell and civil rights activist James Peck, were housed there for refusing to enter the military draft in the early 1940s.^[2][3][4] Robert Henry Best served most of his life sentence at FCI Danbury after being convicted of treason in 1948 for making propaganda broadcasts for the Nazis during the war. Screenwriter Ring Lardner Jr., a member of the Hollywood 10, a group of filmmakers who were charged with contempt of Congress in 1947 for refusing to answer questions regarding their alleged connections with the Communist Party USA, served 9 months there.^[5]

Beginning in the 1970s, the Yale Law School began providing legal services for prisoners at FCI Danbury.^[6] As of the 2010s, Yale students and professors still regularly visit the facility.^[7]

FCI Danbury became exclusively for female inmates in 1993.^[8] This was because there was a lack of space for women in the Northeastern United States and due to the growth in the number of female prisoners.^[9]

In August 2013, the Federal Bureau of Prisons announced that FCI Danbury was going to be reverted to an all-male facility to alleviate overcrowding across the entire federal prison system. The female inmate population will be transferred to the Federal Correctional Institution, Aliceville in Alabama, which opened in 2013 and has over 1,500 low-security beds for female inmates. It was estimated that the change would be completed by December 2013.^[10][11][12] However, female inmates were not transferred to other facilities until April 2014.

FCI Danbury and its camp were the only federal prisons in the Northeast which housed women, and the repurposing would further promote an imbalance of women's prisoner space within the BOP system.^[7] In August 2013 11 senators from the Northeast sent a letter to the BOP director criticizing the move, since it would mean there would be no facility for female federal prisoners from the Northeast; the move would mean that all of the women would be far from their families and loved ones. In November of that year several senators announced that at FCI Danbury the BOP would install a new low security camp for women and convert an existing minimum security camp into a low security camp for women to remedy the issue.^[6] As of August 2014 there was no timeline for the installation of the new women's facilities,^[13] no new construction had yet occurred at FCI Danbury. U.S. citizens would be eligible for the camps, but non-U.S. citizens would still be incarcerated farther away.^[6] As of that time there were no federal women's prisons left in the Northeast.^[7] Orange Is the New Black: My Year in a Women's Prison writer Piper Kerman criticized the move in an op-ed in The New York Times.^[14] A new $25 million women's facility was completed and began accepting female inmates in December 2016.^[15]

FCI Danbury is located in southwestern Connecticut, approximately 55 miles (89 km) from New York City,^[16] 60 miles (97 km) from Hartford, Connecticut, and 150 miles (240 km) from Boston, Massachusetts.^[9]

The facility is accessible to a MetroNorth station fewer than 4 miles (6.4 km) from the facility. Four Amtrak stations are within 30 miles (48 km) from the facility.^[9]

The prison had at one point included athletic facilities such as a running track, a soccer field, handball courts, a baseball diamond, and a handball field, since there is a large amount of outdoor area in the FCI Danbury property.^[9]

Prior to the facility's conversion it offered General Education Development (GED) programs, paralegal classes, a group therapy program for people with post-traumatic stress disorder called the "Bridge Program", and a residential drug abuse program. The prison chaplain, religious groups, and volunteer groups had offered educational and other programming. In addition, prior to 1999 the prison hosted a "children's day" so inmates could spend time with their children.^[9]

The fictional Litchfield Prison in Upstate New York in the Netflix original television series Orange Is the New Black is based in part on FCI Danbury, where Piper Kerman, who wrote the memoir on which the series is based, was incarcerated in 2004 and 2005 after her conviction for money laundering and drug trafficking.^[23]

George Jung served a sentence at FCI Danbury. His incarceration was portrayed in the 2001 film Blow starring Johnny Depp.^[24]

The Weeds character Nancy Botwin serves time at FCI Danbury.^[25]

The Suits character Mike Ross begins Season 6 of the television show in FCI Danbury.^[26]

Gina Zanetakos of The Blacklist was incarcerated at FCI Danbury before she escaped.

In the 1995 movie The American President, Presidential Assistant Lewis Rothschild (played by Michael J. Fox) says "Say what you want. It's always the guy in my job that ends up doing 18 months in Danbury minimum security prison."

In the 2023 series “White House Plumbers” G. Gordon Liddy’s character is promised he’ll serve the prison sentence for his role in the Watergate break-ins at FCI Danbury.
