St Helens () is a large town in Merseyside, England, with a population of 117,308. It is the administrative centre of the Metropolitan Borough of St Helens which had a population of 183,200 at the 2021 Census.
The town is 6 miles (10 kilometres) north of the River Mersey, in the south-west part of historic Lancashire. The town was initially a small settlement within the historic county's ancient hundred of West Derby in the township of Windle but by the mid-1700s the town had developed into a larger urban area beyond the townships borders. By 1838 the council was formally made responsible for the administration of Windle and the three other townships of Eccleston, Parr and Sutton that were to form the town's traditional shape. In 1868 the town was incorporated as a municipal borough, then later became a county borough in 1887. In 1974 the town was made a metropolitan borough within the new Metropolitan County of Merseyside by the Local Government Act 1972, with an expanded administrative responsibility for several nearby towns and villages.
