The Burnley, Nelson, Rossendale and District Textile Workers' Union (BNRDTWU) was a trade union representing cotton industry workers in the Burnley and Nelson areas of Lancashire in England. The union was formed in 1966 with the merger of the Burnley and District Weavers', Winders' and Beamers' Association and the Nelson and District Weavers' Association, initially as the Burnley, Nelson and District Textile Workers' Union. The Padiham and District Weavers', Winders' and Warpers' Association and the Rossendale Valley Textile Workers' Association joined in 1977, and the union adopted its final name.
