A mill town, also known as factory town or mill village, is typically a settlement that developed around one or more mills or factories (usually cotton mills or factories producing textiles).
In the United Kingdom, the term "mill town" usually refers to the 19th century textile manufacturing towns of northern England and the Scottish Lowlands, particularly those in Lancashire (cotton) and Yorkshire (wool).
The British textile industry never fully recovered after the Great Depression, and its decline continued after the Second World War when it was unable to compete with the growing Indian textile industry. It is said that Gandhi was jeered when he visited mill towns on his 1931 tour of Britain, as many locals blamed his policies for causing unemployment. However, American journalist William L Shirer wrote of the mill hands that 'they instinctively recognised in him [Gandhi], a man who devoted his life to helping the poor. They gave him a tumultuous welcome".  There are still a few mills left in operation today. Some mill buildings have conservation orders on them, and some have been converted for other uses.
Some mill towns have a symbol of the textile industry in their town badge. Some towns may have statues dedicated to textile workers (e.g. Colne ) or have a symbol in the badge of local schools (e.g. Ossett School).

On his tour of northern England in 1849, Scottish publisher Angus Reach said:
In general, these towns wear a monotonous sameness of aspect, physical and moral... In fact, the social condition of the different town populations is almost as much alike as the material appearance of the tall chimneys under which they live. Here and there the height of the latter may differ by a few rounds of brick, but in all essential respects, a description of one is a description of all.—Angus Reach, Morning Chronicle, 1849
Beginning with technological information smuggled out of England by Francis Cabot Lowell, large mills were established in New England in the early to mid 19th century. Mill towns, sometimes planned, built and owned as a company town, grew in the shadow of the industries. The region became a manufacturing powerhouse along rivers like the Housatonic, Quinebaug, Shetucket, Blackstone, Merrimack, Nashua, Cocheco, Saco, Androscoggin, Kennebec or Winooski.
- "In the nineteenth century, saws and axes made in New England cleared the forests of Ohio; New England ploughs broke the prairie sod, New England scales weighed wheat and meat in Texas; New England serge clothed businessmen in San Francisco; New England cutlery skinned hides to be tanned in Milwaukee and sliced apples to be dried in Missouri; New England whale oil lit lamps across the continent; New England blankets warmed children by night and New England textbooks preached at them by day; New England guns armed the troops; and New England dies, lathes, looms, forges, presses and screwdrivers outfitted factories far and wide." - Jane Jacobs, The Economy of Cities, 1969
In the 20th century, alternatives to water power were developed, and it became more profitable for companies to manufacture textiles in southern states where cotton was grown and winters did not require significant heating costs. Finally, the Great Depression acted as a catalyst that sent several struggling New England firms into bankruptcy.
