Cromford Mill was the first water-powered cotton spinning mill developed by Richard Arkwright in 1771 in Cromford, Derbyshire, England, which laid the foundation of his fortune and was quickly copied by mills in Lancashire, Germany and the United States. It forms the centrepiece of the Derwent Valley Mills, now a World Heritage Site.
The mill structure is classified as a Grade I listed building, it was first classified in June 1950.
