The Federal Penitentiary Service (FSIN, Russian: Федеральная служба исполнения наказаний (ФСИН), Federalnaya Sluzhba Ispolneniya Nakazaniy) is a federal agency of the Ministry of Justice of Russia responsible for correctional services.

The FSIN is the federal authority for the detention of suspected and convicted persons, the security and maintenance of prisons in Russia, the transport of prisoners, and rehabilitation programs. As of March 2022, it operates 872 institutions (204 pre-trial SIZO institutions, 642 corrective colonies, 8 prisons, 18 juvenile colonies), with pre-trial detention facilities housing adult and juvenile offenders of various security levels, with the majority of penal facilities being corrective labor colonies. Its head office is located at Zhitnaya Street 14 in Yakimanka District, Central Administrative Okrug, Moscow.

The FSIN was established in 2004 as a new federal correctional service agency for the Ministry of Justice to replace the Soviet-era Main Administration for the Execution of Punishments (Главное управление исполнения наказаний, GUIN), formerly of the Ministry of Internal Affairs, and received its current name in 2006. It claims succession from the Main Prisons Directorate of the Russian Empire founded in 1879, and directly succeeds the correctional services of the Ministry of Internal Affairs of the Soviet Union including the Gulag agency.

The Federal Penitentiary Service is considered to be successor to the Main Prison Administration, established on 27 February 1879 as the first government body dealing with maintenance and security of detention and prison facilities in the Russian Empire. On 13 December 1895, the Main Prison Administration was transferred from the Interior Ministry to the Ministry of Justice of the Russian Empire. Following the October Revolution, a new prison administration was established by the Bolsheviks with a system composed mainly of forced labor camps across the Soviet Union. On 7 April 1930, the Gulag agency was established which oversaw an expansion of the labor camp system in the Soviet Union. In 1960, the Main Administration for Execution of Punishments (GUIN) was founded under the Ministry of Internal Affairs of the Soviet Union following the dissolution of the Gulag agency. After the dissolution of the Soviet Union in 1991, Russia maintained GUIN unchanged as part of its own Ministry of Internal Affairs until 1998, when the prison service was returned to the Ministry of Justice after nearly a century. The FSIN was established in 2004 as part of various administrative reforms occurring in Russia reforming executive bodies from 2004 to 2005, maintaining the GUIN name but specially re-created for the Ministry of Justice. In 2006, the FSIN received its current name as the Federal Service for the Execution of Punishments (Russian: Федеральная служба исполнения наказаний (ФСИН)) under the Russian Ministry of Justice. The FSIN is commonly known in English as the Federal Penitentiary Service.
