The United Federation of Christian Trade Unions in Germany (German: Gesamtverband der christlichen Gewerkschaften Deutschlands, GcG) was a national trade union federation in Germany.
The federation was established in 1901 by 23 independent unions.
It initially had a membership of 77,000, but grew to 350,000 in 1912, and then peaked at 1,100,000 in 1919.
While it was open to all Christians, 80% of its membership was Catholic.
The federation worked closely with the Centre Party, until in 1933 it was dissolved by the Nazi government.
