The Progressive Labor Party (PLP) is an anti-revisionist Marxist–Leninist communist party in the United States. It was established in January 1962 as the Progressive Labor Movement following a split in the Communist Party USA, adopting its new name at a convention held in the spring of 1965. It was involved in the anti-Vietnam War movement of the 1960s and early 1970s through its Worker Student Alliance faction of Students for a Democratic Society.

The PLP publishes a fortnightly newspaper, Challenge.
