Crowfield Windmill is a smock mill at Crowfield, Suffolk, England which has been conserved.

Crowfield Windmill is a three-storey smock mill on a single-storey brick base. It had four patent sails and the boat-shaped cap was winded by a fantail. It has two pairs of underdrift millstones which are mounted on a hurst frame.
