Thelnetham Windmill, also known as Button's Mill is a Grade II* listed^[1] tower mill constructed of brick. The windmill is located at Thelnetham, Suffolk, England. It was built in the early nineteenth century to grind wheat into flour. Thelnetham windmill worked by wind power until 1924, latterly on two sails, after which it became derelict.

In 1979, a group of enthusiasts purchased Thelnetham windmill for restoration. Numerous volunteers helped to restore the mill to full working order over an eight-year period. The mill is open to the public, and flour ground at the mill can be bought at the site.

The mill is a small four storey tower mill with Patent sails and winded by a fantail. It drives two pairs of millstones, with a third pair driven by an auxiliary engine.
