The Communist League of Struggle (CLS) was a small communist organization active in the United States during the 1930s. Founded by Albert Weisbord and his wife, Vera Buch, who were veterans of the Left Socialist movement and the Communist Party USA, the CLS briefly affiliated with Leon Trotsky independently of the Communist League of America. It was affiliated to the International Bureau of Revolutionary Youth Organizations until 1935. The small group dwindled and quietly was terminated in the spring of 1937.
