无政府工团主义（英语：Anarcho-syndicalism）是无政府主义中着重在劳工运动的一门学说。 19世纪末起源于法国，后传播到西班牙、意大利、瑞士、美国等地。「Syndicalisme」是法文单字，源自希腊文，意为「工会」 – 因此译为「工团主义」。工团主义是一种非主流的经济制度。无政府工团主义视它为一股能带来革命性社会变革的潜在力量，将成为由工人民主自治，取代资本主义与国家的新社会。无政府工团主义者将薪资制度视为「薪资奴役」（Wage slavery），企图废除。另外，他们认为国家或私人对于生产工具的拥有权将导致阶级差异。无政府工团主义得名于法国左翼组织法国工团联合会。代表人物有法国人若·索列尔等。

Anarcho-syndicalism (also referred to as revolutionary syndicalism) is a theory of anarchism which views revolutionary industrial unionism or syndicalism as a method for workers in capitalist society to gain control of an economy and use that control to influence broader society. Syndicalists consider their economic theories a strategy for facilitating worker self-activity and as an alternative co-operative economic system with democratic values and production centered on meeting human needs.
