The Ligue Communiste Révolutionnaire (LCR, "Revolutionary Communist League") is a French Trotskyist political party. It is the French section of the United Secretariat of the Fourth International. It publishes the weekly newspaper Rouge and the journal Critique Communiste.
It was founded in 1968 when its forerunner the Communist League (Ligue Communiste) was banned.
Its official spokesman is Alain Krivine, a member of the European Parliament, but Olivier Besancenot was the candidate for the 2002 French presidential election.
An ongoing issue is the possibility and conditions of an electoral alliance with fellow Trotskyist party Lutte Ouvrière. In the past the two have at times run joint candidates (for example in the last European elections), and at times run separately (for example in the last presidential elections).
LCR militants openly work within left-wing groups such as ATTAC and the Solidaires Unitaires Démocratiques trade unions.
Its recent congress voted to abandon use of the term "dictatorship of the proletariat" to describe its political aims. The group includes members of other Trotskyist tendencies who are able to organise openly within its ranks to gain support for its views.
