The Tobacco Workers' Union was a trade union representing workers in all areas of the tobacco industry in the United Kingdom. The union was founded in 1834 in London as the Friendly Society of Operative Tobacconists. Two years later, it expanded its membership to include tobacco cutters, dryers and stovers and was renamed the United Tobacconists Society. In 1851, it expanded again to include cigarette makers, and in 1881 it took another name, the United Operative Tobacconists throughout the Kingdom. For much of this period, the union was based in Liverpool at the houses of its successive general secretaries, but in 1918 it relocated to London.
