The National Caucus of Labor Committees (NCLC) is a political organization in the United States founded and controlled by political activist Lyndon LaRouche until his 2019 death. LaRouche sometimes described the NCLC as a "philosophical association". It is the main organization within the LaRouche movement. LaRouche was the association's leader, and the political views of the NCLC are virtually indistinguishable from those of LaRouche.
