Amalgamated Textile Workers' Union

The Amalgamated Textile Workers' Union (ATWU) was a trade union in Great Britain.

The union was founded in 1974, when the Amalgamated Weavers' Association merged with the National Union of Textile and Allied Workers. The Amalgamated Textile Warehousemen's Association developed close links with the new union, and the two shared a general secretary.

With widespread redundancies in the industry, the union lost two-thirds of its members before it merged into the General, Municipal, Boilermakers and Allied Trades Union in 1985. Based in Rochdale, the union's final general secretary was Jack Brown.
