英國政黨，過去與工會的連結關係促使其在創造國家經濟繁榮和提供社會服務上扮演活躍的角色。與保守黨處於相對地位，工黨自20世紀初以來為英國主要的民主社會黨。1900年英國職工大會與獨立工黨（1893年成立）共同組成「工人代表委員會」，1906年改名工黨。1918年成為有民主章程的社會黨，到了1922年時取代自由黨成為正式的反對黨。1924年麥克唐納在自由黨支持下組成第一屆工黨政府。工黨自1935年開始喪失權力，直到1945年重獲選舉勝利，由艾德禮組成的政府（持續至1951年）建立了社會福利體系，包括國民保健署和廣泛的工業國有化。工黨在威爾遜（1964～1970）和賈拉漢（1974～1979）的領導下重獲政權，但因為經濟問題和與工會間越來越惡劣的關係而崩潰。1983年富特提出的激進政策使工黨大敗。金諾克（生於1942年）雖將黨的立場移向中庸，但只有在1997年布萊爾和他的「新工黨」議題成功地讓工黨重回執政地位。
Labour Party
British political party whose historic links with trade unions have led it to promote an active role for the state in the creation of economic prosperity and the provision of social services. In opposition to the Conservative Party, it has been Britain's major democratic socialist party since the early 20th century. In 1900 the Trades Union Congress and the Independent Labour Party (founded 1893) established the Labour Representation Committee, which took the name Labour Party in 1906. In 1918 it became a socialist party with a democratic constitution, and by 1922 it had supplanted the Liberal Party as the official opposition party. In 1924 James Ramsay MacDonald formed the first Labour government, with Liberal support. The party was out of power from 1935 until a spectacular recovery in 1945 brought in Clement R. Attlee's government (until 1951), which introduced a system of social welfare, including a national health service, and extensive nationalization of industry. Labour regained power under Harold Wilson (1964-70) and later James Callaghan (1974-79), but foundered because of economic problems and worsening relations with its trade-union allies. In 1983 Michael Foot's radical program resulted in a massive Labour defeat. Neil Kinnock (born 1942) moved the party toward the center, but only in 1997 did Tony Blair and his “New Labour” agenda succeed in returning Labour to power.
