威根早在十二世纪已有人居住。18世纪正值工业革命年代，威根乃英国的工业城镇，其中第一家亨氏茄汁黄豆罐头工厂正在于此，同时也有大量纺织厂在此设立。二次大战后随着英国制造业式微，威根地位逐渐下降。

Wigan /ˈwɪɡən/ is a town in Greater Manchester, England. It stands on the River Douglas, 7.9 miles (13 km) south-west of Bolton, 10 miles (16 km) north of Warrington and 16 miles (25.7 km) west-northwest of Manchester. Wigan is the largest settlement in the Metropolitan Borough of Wigan and is its administrative centre. The town of Wigan had a total population of 97,000 in 2011, whilst the wider borough has a population of 318,100. Historically in Lancashire, Wigan during classical antiquity was in the territory of the Brigantes, an ancient Celtic tribe that ruled much of what is now northern England. The Brigantes were subjugated in the Roman conquest of Britain during the 1st century, and it is asserted that the Roman settlement of Coccium was established where Wigan lies. Wigan is believed to have been incorporated as a borough in 1246 following the issue of a charter by King Henry III of England. At the end of the Middle Ages it was one of four boroughs in Lancashire possessing Royal charters; the others were Lancaster, Liverpool, and Preston.
