Christian Klar (born 20 May 1952 in Freiburg im Breisgau) is a convicted murderer and former West German terrorist. He became a leading member of the second generation Red Army Faction (RAF) between the 1970s and 80s. He had been incarcerated since 1982 in a Bruchsal prison, but was released on 19th of December 2008, after serving over 26 years of his life sentence.

The son of a teacher and vice-principal, Klar attended school in Lorrach, and in 1972 graduated from a school in Ettlingen. He went on to study History and Philosophy in the University of Heidelberg, and became, for awhile, a member of a young democratic movement.

Around 1973 he moved to a Karlsruhe flat with his girlfriend Adelheid Schulz, Gunter Sonnenberg and Knut Folkerts (who would all subsequently become RAF terrorists) and in 1974 he took part in the occupation of the Hamburg Amnesty International offices protesting against the detention of RAF prisoners.
