Fritz Teufel (17 June 1943 – 6 July 2010) was a prominent figure in the West German political left of the 1960s. One of the founders of Kommune 1, Teufel cultivated a theatrical, humorous public image—encapsulated in his idea of the "Spaßguerilla" ("fun guerrilla"). In the 1970s he rejected this image and became involved with the violent Movement 2 June. He was jailed several times in the 1960s and 1970s.
