New Hall Mill is a watermill in Walmley, in Sutton Coldfield, West Midlands.

It has been restored to working condition, and visitors can see the mill in operation.

[2] The mill is within, but not part of, New Hall Valley Country Park.

It originally milled wheat to make flour; more recently, when it could not compete with larger mills, it became a hammermill, powered by a diesel engine, to produce grist or animal feed.

Other machinery in the mill is powered by a Ruston & Hornsby diesel engine.
