This is a list of the cotton and other textile mills in Derbyshire, England. The first mills were built in the 1760s in the Derwent Valley by Arkwright and Strutt, and were powered by the water of the River Derwent. The abundance of water from the River Etherow and its tributaries led to mills being built in Longdendale and Glossopdale, and similarly along the River Wye in Millers Dale. As the industry developed, the mills changed hands, were demolished, were converted to use steam, or consolidated into larger units. They changed their names and their functions. Water-powered mills were smaller than the later steam-powered mills found in Greater Manchester. Parts of Derbyshire have been subsumed into Stockport.
