René Belin (14 April 1898 – 2 January 1977) was a French trade unionist and politician.
In the 1930s he became one of the leaders of the French General Confederation of Labour.
He was strongly opposed to communism.
In the prelude to World War II (1939–45) he favored a policy of appeasement.
After the defeat of France, he was Minister of Industrial Production and Minister of Labour in the collaborationist Vichy Government, holding the latter office until April 1942.
He oversaw the destruction of unionism.
As a result, he was expelled from the CGT in 1944.
After the war he tried to form an anti-communist union movement, but with limited success.
