Reeducation camp (Vietnamese: trại học tập cải tạo) is the official title given to the prison camps operated by the government of Vietnam following the end of the Vietnam War. In such camps, the government imprisoned several hundred thousand former military officers and government workers from the former government of South Vietnam. Reeducation as it was implemented in Vietnam was seen as both a means of revenge and as a sophisticated technique of repression and indoctrination, which developed for several years in the North and was extended to the South following the 1975 Fall of Saigon.
