The Trotskyist League was a United States Trotskyist group which existed in the US from 1991 to 2002.
A splinter of the Revolutionary Workers League, the Trotskyist League was the US section of the International Trotskyist Opposition. Its strongest base was in Detroit, where it had some members active as trade unionists in the car industry. Other local groups existed in Ann Arbor and Cincinnati. Members were active in Anti-Racist Action.
In 2002 it joined Solidarity. Its political descendant is the "Refoundation and Revolution" current, which is the US section of the Co-ordinating Committee for the Refoundation of the Fourth International and remains part of Solidarity.
