Ashton windmill is a tower mill in Chapel Allerton, Somerset, England.

The mill is opened two afternoons a week in summer by a group of local volunteers and is free to visit, although donations are welcome.

The machinery was replaced with that from Moorlinch Mill, the original thatch was reframed and clad with corrugated iron, two of the broad sails were replaced with spring sails and iron hoops around the building were added.

Ashton Windmill ceased to operate in 1927 because of lower corn prices and competition from large steam-powered mills.

The mill was renovated in 1958, when the stonework was restored and a new boat-shaped roof, new doors and new sails were fitted.
