Bacup is a town within the Rossendale borough of Lancashire, England. It is located amongst the South Pennines, along Lancashire's eastern boundary with West Yorkshire. The town sits within a rural setting in the Forest of Rossendale, amongst the steep-sided upper-Irwell Valley, through which the River Irwell passes. It is east of Rawtenstall, north of Rochdale, and east of Preston. At the time of the United Kingdom Census 2001, Bacup—-which encompasses the outlying communities of Britannia, Stacksteads, Rockcliffe, Trough Gate and Weir (all re-directed here)—had a population of 12,763.
Bacup emerged as a settlement following the Anglo-Saxon settlement of Britain in the Early Middle Ages. For centuries, Bacup was a small and obscure centre of domestic flannel and woollen cloth production, and many of the original weavers' cottages survive today as listed buildings. Following the Industrial Revolution Bacup became a mill town, its landscape dominated by distinctive and large rectangular woollen and cotton mills. Bacup received a charter of incorporation in 1882, giving it municipal borough status and its own elected town government, consisting of a mayor, aldermen and councillors to oversee local affairs.
In 1974 Bacup became part of the borough of Rossendale.
