Hermann Klebe (born 16 August 1878) was a German trade unionist.
Klebe became a naval engineer, and joined the Central Union of Machinists and Stokers. In 1919, he became the president of the union.[1] In 1927, he led the formation of the International Federation of Enginemen and Firemen, becoming its general secretary.[2] He lost all his trade union posts in 1933, when the German unions were banned by the Nazi government. He fled to Denmark, where he continued involvement in trade unionism.[3]
