The Himriksmole, also known as Groene Ster after the recreational area and nature reserve where it is located, is a drainage mill near the village of Tytsjerk, Friesland, Netherlands.

The mill is listed as a Rijksmonument, number 35675, and is used to raise the water level in the nature reserve.

It was replaced by an electric pumping station and moved in 1952 to Rijperkerk and in 1977 to its current location, where it was put to a new use, supplying water to the nature reserve.

The four common sails have a span of 11 metres (36 ft 1 in) and are carried on a cast-iron windshaft.

The brake wheel on the windshaft drives the wallower at the top of the upright shaft in the body (on a spinnenkop called the head), which passes through the main post into the substructure.
