Samuel Webb is an American activist and political leader, who served as the Chairman of the Communist Party USA from 2000 to 2014, succeeding the party's longest running leader Gus Hall. Webb did not accept nomination to be reelected as chairman at the 30th National Convention of the Communist Party USA in 2014, at which John Bachtell was elected the party's new chairman. Webb continued to serve on the party's National Committee until 2016.

Gus Hall was the General Secretary of the Communist Party USA (CPUSA) and a perennial candidate for president of the United States. He was the Communist Party nominee in the 1972, 1976, 1980, and 1984 presidential elections. As a labor leader, Hall was closely associated with the so-called "Little Steel" Strike of 1937, an effort to unionize the nation's smaller, regional steel manufacturers. During the Second Red Scare, Hall was indicted under the Smith Act and was sentenced to eight years in prison. After his release, Hall led the CPUSA for over 40 years, often taking an orthodox Marxist–Leninist stance.
