The German Transport Workers' Union (German: Deutscher Transportarbeiter-Verband, DTV) was a trade union representing transport workers in Germany.

The union was founded in 1897 as the Association of Commercial, Transport and Communication Workers, and it affiliated to the General Commission of German Trade Unions.

It grew rapidly, with the German Railway Workers' Union joining in 1908, and the Union of Dockers of Germany and the Central Union of Sailors of Germany both joining in 1910, taking membership to 230,000 by 1913.

After World War I, it affiliated to the new General German Trade Union Confederation.

[1][2] Throughout its existence, the union was led by Oswald Schumann.
