Alsager ( AWL-say-jər) is a town and civil parish in the unitary authority of Cheshire East and the ceremonial county of Cheshire, England, to the northwest of the city of Stoke-on-Trent, and east of the railway town of Crewe. The town has a population of 11,775.
The civil parish is bordered by the parishes of Betchton to the north, Church Lawton to the north-east and east, Kidsgrove in Staffordshire to the south-east, Audley Rural, in Staffordshire to the south, Barthomley to the south-west, Haslington to the west, and Hassall to the north-west.
In the centre of Alsager is a lake, The Mere. This isolated pool, once the focal point of the town, is only accessible by two fenced public viewing areas and by local residents who have gardens adjoining the waters.
Alsager has hosted an annual Summer carnival since 1998. Until June 2009 the summer carnival was located in Milton Park, but it had since moved to the Alsager School playing fields to increase capacity, until moving back to Milton Park in 2017.
