Bolton-le-Sands is a large village and civil parish of the City of Lancaster in Lancashire, England. The parish had a population of 4,098 recorded in the 2001 census, increasing to 4,127 at the 2011 Census. Referred to as Bodeltone in the Domesday book, the village was known as Bolton until the arrival of the railways, when the name was changed to Bolton-le-Sands to differentiate from similarly named towns on the same line, such as Bolton which was then a part of Lancashire and called Bolton-le-Moors.
