The Gulag Archipelago: An Experiment in Literary Investigation is a three-volume non-fiction series written between 1958 and 1968 by Russian writer Aleksandr Solzhenitsyn, a Soviet dissident. It was first published in 1973 by the Parisian publisher YMCA-Press, and it was translated into English and French the following year.

Solzhenitsyn constructed his highly detailed narrative from various sources including reports, interviews, statements, diaries, legal documents, and his own experience as a Gulag prisoner.

Aleksandr Isayevich Solzhenitsyn was a Russian writer and prominent Soviet dissident who helped to raise global awareness of political repression in the Soviet Union, especially the Gulag prison system.
