The General Confederation of Labour (French: Confédération Générale du Travail, pronounced [kɔ̃fedeʁɑsjɔ̃ ʒeneʁal dy tʁavaj], CGT) is a national trade union center, founded in 1895 in the city of Limoges. It is the first of the five major French confederations of trade unions.

It is the largest in terms of votes in the Labour Court elections (34.0% in the 2008 election), and second largest in terms of membership numbers.

Its membership decreased to 650,000 members in 1995–1996 (it had more than doubled when François Mitterrand was elected president in 1981), before increasing today to between 700,000 and 720,000 members, slightly fewer than the Confédération Française Démocratique du Travail (CFDT).

According to the historian M. Dreyfus, the direction of the CGT is slowly evolving, since the 1990s, during which it cut all organic links with the French Communist Party (PCF), in favour of a more moderate stance. The CGT is concentrating its attention, in particular since the 1995 general strikes, to trade-unionism in the private sector.

The CGT was founded in 1895 in Limoges from the merger of the Fédération des bourses du travail (Federation of Labour Councils) and the Fédération nationale des syndicats (National Federation of Trade Unions). Auguste Keufer was amongst the founders and became the first treasurer.

At the end of Henri Krasucki's term (1982–1992), he began to distance himself from the French Communist Party (PCF). His successor, Louis Viannet, did the same, going as far as resigning from the political bureau of the party.

CGT General Secretary Phillipe Martinez announced that the union will support the week of climate action beginning on 20 September 2019.

In 2023, the CGT was involved in the interunion social movement against pension reform which organized strikes and protests in 300 towns across France, and wrote to Emmanuel Macron requesting negotiations, then, having not been received, mediation and a suspension of the 2023 French pension reform bill.
