Sankey for Penketh railway station, also known as just Sankey, is a railway station in the west of Warrington, Cheshire, England, serving the Great Sankey, Penketh and Whittle Hall areas of the town. The station, and all trains serving it, are operated by Northern Trains. It is designated by English Heritage as a Grade II listed building.

The Cheshire Lines Committee (CLC) was formed in the 1860s and became the second-largest joint railway in Great Britain. The committee, which was often styled the Cheshire Lines Railway, operated 143 miles (230 km) of track in the then counties of Lancashire and Cheshire. The railway did not become part of the Big Four during the implementation of the 1923 grouping, surviving independently with its own management until the railways were nationalised at the beginning of 1948. The railway served Liverpool, Manchester, Stockport, Warrington, Widnes, Northwich, Winsford, Knutsford, Chester and Southport with connections to many other railways.
