Longshaw is a small residential and agricultural area within Billinge Higher End at the western boundary of the Metropolitan Borough of Wigan, in Greater Manchester, England.

After being divided into two townships, Billinge Chapel End and Billinge Higher End in the Wigan Poor Law Union, in 1872 Billinge Local Board of Health was established for the area of these two townships and two detached parts of Winstanley township (one known as Blackley Hurst and the other situated in the Carr Mill area, both lying within the area of Billinge Chapel End township).

In 1974 Longshaw, Billinge Higher End and most of Winstanley became part of the Metropolitan Borough of Wigan in Greater Manchester, with Billinge (including the remainder of Winstanley) becoming part of the Metropolitan Borough of St Helens in Merseyside.
