The Communist League of West Germany (Kommunistischer Bund Westdeutschland; KBW) was a Maoist organization in West Germany which existed from 1973 until 1985. The KBW contested the general elections in 1976 and 1980 in West Germany and was rated as the strongest of the German Maoist parties from 1974 until 1981. After 1982 the KBW was virtually inactive and was finally dissolved completely in 1985.
A number of the former KBW members became more conservative politicians ("Realos") in The Greens: Reinhard Bütikofer, Winfried Kretschmann, Ursula Lötzer, Krista Sager, Ralf Fücks und Ulla Schmidt.
