Chí Hòa Prison (Vietnamese: Khám Chí Hòa or Nhà Tù Chí Hòa) is a functioning Vietnamese prison located in Ho Chi Minh City, Vietnam. The prison is an octagonal building on a 7-hectare site consisting of detention rooms, jail cells, prison walls, watchtowers, facilities and prisoner's farmlands. The prison is one of 12 national prisons in Vietnam. Originally built by the French Indochina colonial government in 1943 (or 1939) to replace the Saigon Grand Prison, the prison was extensively used by all succeeding governments of Vietnam. Due to its complex and effective architecture, the prison is considered one of the highest security prisons in Vietnam as there were only two successful prison-breaks in its history.
