Ypey Mole is a smock mill in Ryptsjerk, Friesland, Netherlands which was built in 1911.

Ypey Mole was originally built in 1858 at Zwartewegsend, where it was in use until the Autumn of 1958 when the sails were damaged.

The mill was restored in 1959 by millwright De Roos of Leeuwarden, Friesland.

The mill was moved to its current site in 1981 and restored by millwright Tacoma of Stiens, Friesland.

The lower crown wheel, which has 35 cogs is carried on the axle of an Archimedes' screw, which is used to drain the polder.
