Swinley is an urban suburb of Wigan in Greater Manchester, England. The area was mainly developed during the late Victorian and Edwardian periods, from around 1885 until the end of the interwar years, along a green corridor centred on the section of the Chester–Lancaster Roman Road known as Wigan Lane. This route leads northwards from the original 1246 Royal Charter boundary of the Borough of Wigan towards the parish of Standish, lying between neighbouring industrial districts of mills, mines, and ironworks.
