7, also called the Koggemolen, is a windmill on the Kolkweg in Aartswoud, Netherlands that has been restored to working order.

The mill is to the south of the Westfriesedijk (part of the Westfriese Omringdijk) just outside Aartswoud.

The mill is probably the oldest of its type in North Holland, dating to c. 1541.

Restoration of the internal machinery was completed in 2009, and the mill was again able to pump water.

The cap carries four common sails of 23.40 metres (76 ft 9 in) span.
