The National Campaign Committee for Unemployment Insurance (NCCUI) was a mass organization of the Communist Party USA established in October 1930 in an effort to build a radical movement around the issue of unemployment insurance, thereby advancing the American Communist Party's cause. Headed by Alfred Wagenknecht, the NCCUI gathered a claimed 1.4 million petition signatures, which were presented to United States Congress amidst a heightened police presence on February 10, 1931.
